The arbor vitae serves a crucial function in the brain. The name comes from Latin and literally translates to “tree of life.” The name accurately describes the appearance of the white matter that serves to bring sensory and motor information to the cerebellum.

Subsequently, question is, how does the cerebellum develop? During the early stages of embryonic development, the brain starts to form in three distinct segments: the prosencephalon, mesencephalon, and rhombencephalon. The cerebellum arises from two rhombomeres located in the alar plate of the neural tube, a structure that eventually forms the brain and spinal cord.

One may also ask, what are the 3 parts of the cerebellum?

There are three functional areas of the cerebellum the cerebrocerebellum, the spinocerebellum and the vestibulocerebellum. Cerebrocerebellum the largest division, formed by the lateral hemispheres.

The white matter in the cerebellum has a branching arrangement that resembles a tree. This structure is named for its appearance.

Important Functional Areas Of The Cerebrum

Cortices of the cerebral cortex have long been divisible by their specific functions. These areas can be defined in terms of the gyri and sulci described above. However, upon investigation of the microscopic structure of the cerebral cortex, there is considerable variation from region to region and that definition of these functional areas is not confined to the boundaries of gyri and sulci, but often cross them. Most of these authors have also worked out maps of the cerebral cortex indicating areas of the differing structure. The best-known scheme is that by Brodmann, who represented different areas of the cortex by numbers.

Do Rabbits Eat Arborvitae

Arborvitae, with their soft, flat-type foliage, are rabbit candy. The lower green foliage is often completely consumed as high as rabbits can reach. If rabbits also gnaw the bark away and dont just eat foliage, branches may die. Evergreens cant regrow or be rejuvenated by heavy pruning the way deciduous shrubs can.

What Is The Function Of The Arbor Vitae

The arbor vitae lies in the center of the cerebellum and is critical in the coordination of the arms, legs and any actions requiring hand-eye coordination. The arbor vitae is made of white matter that transmits information throughout the brain.

The arbor vitae is made up of pink tinted myelinated axons that transmit nerve impulses. The myelin sheaths that cover the axons give the arbor vitae its pink tint from protein and fatty materials. If damage occurs to the myelin sheaths, an individual can end up contracting multiple sclerosis or other diseases. Other issues that can arise in the arbor vitae include cerebellar hemorrhage from tumors and infection from pathogens that lead to ataxia.

The deep cerebellar and the fastigial nuclei are located inside the arbor vitae, as are the emboliform-globose and dentate nuclei. These structures lead to the efferent projections in the cerebellum. The cerebellum sits below the rest of the brain and looks like a separate structure its surface of parallel groves looks quite different from the irregular convolutions of the cerebral cortex. The cerebellum is composed of a continuous layer of tissue that is tightly folded like an accordion.

Meninges Cerebrospinal Fluid And Blood Supply

Like the spinal cord, the brain is covered and partially protected by connective tissue meninges. From outermost to the innermost they are the dura mater, arachnoid mater, and pia mater. The dura mater folds into two layers, a periosteal layer fused to the skull bones, and a meningeal layer. In some areas, these layers are separated by a dural sinus, a space used to collect blood. Some areas may also contain a subarachnoid space or a subdural space.

Meninges. Cerebrospinal fluid is a clear, colorless liquid that bathes the external surfaces of the brain. It is constantly produced, flows through the network of ventricles, and is reabsorbed. CSF functions in cushioning and supporting the brain by buoyance, and in chemical stability of the brain, by transporting nutrients and wastes respectively.

The ependymal cells lining the ventricles produce the CSF. Then the CSF flows throughout the brain in the ventricles. Each cerebral hemisphere contains a lateral ventricle. Each lateral ventricle drains through an interventricular foramen into the third ventricle. The third ventricle sits in the midbrain region. The CSF then flows into the cerebral aqueduct to the fourth ventricle. Before being reabsorbed, the CSF enters one of two lateral apertures or a median aperture, and then fills the subarachnoid space. Reabsorption of CSF occurs there by the arachoid villi and enters the venous blood.

The Hypothalamus Manages Sensory Impulses Controls Emotions And Regulates Internal Functions

Cerebellum – Brain

The hypothalamus is part of the diencephalon, a region of the forebrain that connects to the midbrain and the cerebrum. The hypothalamus helps to process sensory impulses of smell, taste, and vision. It manages emotions such as pain and pleasure, aggression and amusement. The hypothalamus is also our visceral control center, regulating the endocrine system and internal functions that sustain the body day to day. It translates nervous system signals into activating or inhibiting hormones that it sends to the pituitary gland. These hormones can activate or inhibit the release of pituitary hormones that target specific glands and tissues in the body. Meanwhile, the hypothalamus manages the autonomic nervous system, devoted to involuntary internal functions. It signals sleep cycles and other circadian rhythms, regulates food consumption, and monitors and adjusts body chemistry and temperature.

Overview Of The Brain

The large brain of humans is perhaps the most important evolutionary advance for the species. At the minimum, it is the characteristic most of us consider the distinguishing characteristic of a human. This module outlines the structural and functional relationships of the human brain.

Superior view of the brain. This work by Cenveo is licensed under a Creative Commons Attribution 3.0 United States .

Lateral view of the brain. This work by Cenveo is licensed under a Creative Commons Attribution 3.0 United States . The dominant portion of the human brain is the cerebrum. It is the large upper part of the brain, distinguished by the gyri and sulci of the surface. The cerebrum is clearly split into left and right hemispheres the split is the deep longitudinal fissure. The cerebrum sits atop and around the midbrain, which leads into the brainstem. Situated essentially behind the midbrain and under the cerebrum is the distinctive cerebellum.

The inside of the brain is characterized by regions of gray matter and white matter. The gray matter is mostly cell bodies, dendrites, and synapses and forms a cortex over the cerebrum and cerebellum, and also forms some nuclei deeper in the cerebrum. White matter is myelinated axons forming tracts.

The cerebral white matter tracts are classified as

  • Projection tracts-from higher to lower, from cerebrum to brainstem and spinal cord
  • Commissural across hemispheres

The gray matter of the cerebral cortex includes:

A Sorting Station: The Thalamus Mediates Sensory Data And Relays Signals To The Conscious Brain

The diencephalon is a region of the forebrain, connected to both the midbrain and the cerebrum. The thalamus forms most of the diencephalon. It consists of two symmetrical egg-shaped masses, with neurons that radiate out through the cerebral cortex. Sensory data floods into the thalamus from the brain stem, along with emotional, visceral, and other information from different areas of the brain. The thalamus relays these messages to the appropriate areas of the cerebral cortex. It determines which signals require conscious awareness, and which should be available for learning and memory.

The Seat Of Consciousness: High Intellectual Functions Occur In The Cerebrum

The cerebrum is the largest brain structure and part of the forebrain . Its prominent outer portion, the cerebral cortex, not only processes sensory and motor information but enables consciousness, our ability to consider ourselves and the outside world. It is what most people think of when they hear the term grey matter. The cortex tissue consists mainly of neuron cell bodies, and its folds and fissures give the cerebrum its trademark rumpled surface. The cerebral cortex has a left and a right hemisphere. Each hemisphere can be divided into four lobes: the frontal lobe, temporal lobe, occipital lobe, and parietal lobe. The lobes are functional segments. They specialize in various areas of thought and memory, of planning and decision making, and of speech and sense perception.

Diencephalon Brainstem And Related Structures

The diencephalon is part of the old brain lying between the cerebrum and the brainstem and is composed of the thalamus, the hypothalamus, and the epithalamus. These can be seen in a midsagittal aspect upon sectioning of the third ventricle. The brainstem is the bridge between the cerebral hemispheres and the spinal cord. It is made up of the midbrain, pons and the medulla oblongata. They are continuous above with the cerebral hemispheres, below with the spinal cord and posteriorly with the cerebellum.

The midsagittal section of the diencephalon and brainstem show some important masses of gray matter projecting onto the median plane. Some nuclei that can be observed include:

  • The thalamic and hypothalamicnuclei bordering the third ventricle.
  • The pineal gland which is the main component of the epithalamus.
  • The superior and inferior colliculi, two posterior bulges situated on either side of the midsagittal line.
  • The nucleus gracilis lying immediately lateral to the posterior median fissure.

Lesions Of The Cerebellum

Arbor Vitae Anatomy

Patients with cerebellar lesions typically exhibit deficits during movement execution. For example, they show intention tremorsa tremor occurring during movement rather than at rest, as seen in Parkinsons disease. Patients may also show dysmetria, i.e., an overestimation or underestimation of force, resulting in overshoot or undershoot when reaching for a target. Another common sign of cerebellar damage is an inability to perform rapid alternating movements.

The anterior and medial aspects of the cerebellum represent information ipsilaterally thus, damage to this region on one side affects the movement on the same side of the body. The posterior and lateral aspects of the cerebellum represent information bilaterally damage to this region has been shown to impair sensorymotor adaptation, while leaving motor control unaffected. In certain instances, a patient experiences a focal lesion. Such localized lesions cause a wide variety of symptoms related to their location in the cerebellum. A striking example is archicerebellar lesions, which cause motor symptoms not unlike those seen during intoxication: uncoordinated movements, swaying, unstable walking, and a wide gait. To avoid suspicion by the police of public drunkenness, American patients who suffer archicerebellar lesions carry identification cards written by their physicians, indicating their medical condition.

Midsagittal Section Of The Brain

The midsagittal section of the brain shows the three major parts of the brain, which are the cerebrum, cerebellum, and brainstem. These brain parts are marked with visible gross features like the gyri and sulci of the cerebrum. They are each also divided into subparts or regions for simplified localization of structures, for example, the brainstem is composed of the midbrain, pons and medulla oblongata, while the cerebrum is divisible into lobes.

Sulci are small grooves that divide and define gyri large grooves, called fissures, divide the cerebral cortex into lobes, and also the cerebrum into the right and left cerebral hemispheres along the midsagittal plane. The fissure involved in this division is called the medial longitudinal fissure. From the midsagittal section of the brain both white and gray matter can be observed, as well as important spaces such as the third and fourth ventricles.
