They occur in different organs of the body. The cerebral cortex contains clearly defined and characteristic brain layers:Lamina molecularis - the surface layerLamina granularis externa (outer granule) - a well-developed layer in the sensitive region, containing Golgi cellsLamina pyramidalis externa (outer layer of the pyramidal cells) - best developed in the precentral partLamina granularis internal (inner granular layer) - consists of tiny Golgi cellsMore items
The brain stem is the oldest and innermost region of the brain.Its designed to control the most basic functions of life, including breathing, attention, and motor responses (Figure 3.8 The Brain Stem and the Thalamus).The brain stem begins where the spinal cord enters the skull and forms the medulla, the area of the brain stem that controls Parietal Lobe 3. It is these connections as well as the connections from the cerebral cortex to the brainstem, spinal cord and nuclei deep within the cerebral hemisphere that form the white matter of the cerebral hemisphere.

Though this cannot be seen directly, different parts of the cortex have different functions (see diagram).
The pial vessels are intracranial vessels on the surface of the brain within the piaarachnoid (also known as the leptomeninges) or glia limitans (the outmost layer of the cortex comprised of astrocytic end-feet) .Pial vessels are surrounded by cerebrospinal fluid (CSF) and give rise to smaller arteries that eventually penetrate into the In humans, it is by far the largest part of the brain. The brain is surrounded by a skull, which is made up of 22 bones - 14 are facial bones and 8 are cranial bones. Human language. The cerebral cortex is the organ of thought. The intermediate types of cortex in which the 6-layered structure can be seen is called homotypical cortex. Which regions of the cerebral cortex are the origin of descending commands that influence internal organs? Hope you could understand the histological structures of animal cerebellum. These movements can be of two types, voluntary and involuntary. Your brain initiates and coordinates various body movements. Lobes of the brain A diagram of the brain identifying the different lobes by color. The surface of the brain, known as the cerebral cortex, is very uneven, characterized by a distinctive pattern of folds or bumps, known as gyri (singular: gyrus), and grooves, known as sulci (singular: sulcus). The cerebral cortex. The emotional brain is centered in the limbic system (diagram) and its connections to the cortex and other subcortical structures. #5. It is the most prominent visible feature of the human brain, and although it. This brain structure reaches its maximum development in primates, is less developed in other animals and is related to the development of more complex cognitive and intellectual activities. The cerebral cortex is the outermost layer of the cerebrum, or its gray matter.

This answer has been confirmed as correct and helpful. The white matter conveys fibers between different parts of the cortex and from other parts of CNS.
It is composed of two cerebral hemispheres that are joined together by heavy, dense bands of fibre called the corpus callosum. The pons connects the cerebral cortex to the medulla and to the cerebellum and serves a number of important functions. Occupying the upper part of the cranial cavity, the cerebral cortex has 4 lobes and is divided into 2 hemispheres that are joined centrally by the corpus callosum. An interesting feature of the cerebral cortex is that its two sides have a contralateral relationship with the bodyfor example, impulses originating on the right side of the cortex are responsible for motor activity on the left side of the body and vice versa. We used transneuronal transport of rabies virus in monkeys and rats to identify regions of cerebral cortex that have multisynaptic connections with a major sympathetic effector, the adrenal medulla.
