Asymmetric tonic neck reflex (ATNR) is the term used to describe the typical movement of a newborn turning its head to the side where the arm and leg are also extended at the same time. On the side facing away from the head, however, the limbs bend in contrast. In addition, the fist on the … Asymmetric Tonic Neck Reflex: Function, Role & Diseases
The prosencephalon is part of the central nervous system and consists of the cerebrum (telencephalon) and diencephalon. In the three vesicle stage of early embryonic development, the prosencephalon represents one of the three primary cerebral vesicles. What is the prosencephalon? The prosencephalon (forebrain) includes two major anatomical subunits: the cerebrum (telencephalon) and the diencephalon (diencephalon). … Prosencephalon: Structure, Function & Diseases
The internal capsule is located in the human brain and consists of nerve fibers that connect deeper areas and the cerebral cortex. The numerous tracts that pass through the internal capsule include the fibrae frontopontinae, the tractus corticospinalis of the pyramidal tract, the fibrae temporopontinae, the tractus corticotectalis, and parts of the auditory and visual … Internal Capsule: Structure, Function & Diseases
Good and clean articulation is essential for the success of communication. Those who can articulate what is said flawlessly are better understood by the interlocutor. Articulation depends primarily on good interaction between the speech tools and the speech center. What is communication? Good and clean articulation is essential for communication to succeed.

It is one of the most important early childhood reflexes and initiates the newborn’s search for the mother’s breast or bottle of milk. The baby turns its head in the direction of the touch and opens … Search Reflex: Function, Tasks, Role & Diseases
The olfactory bulb or bulbus olfactorius processes sensory stimuli from the nose and is part of the olfactory pathway. It is located at the frontal lobe base of the brain and has special types of neurons called mitral, brush, and granule cells. Damage and functional impairment in the olfactory bulb result in various olfactory disorders. … Olfactory Bulb: Structure, Function & Diseases
Human herpesviruses are host-specific viruses of the Herpesviridae family, all of which are human pathogens. In addition to labial herpes, this group of infections includes genital herpes, both of whose pathogens remain in their host for life. An alternation between active and inactive states is characteristic of human herpesviruses of each species. What are human … Human Herpes Viruses: Infection, Transmission & Diseases
The postcentral gyrus is an area of the cerebrum. It is located in the parietal lobe and plays a role in somatosensory processing. Damage to the postcentral gyrus results in astereognosia, which is reflected as disturbances in touch sensitivity, pain and temperature perception, and vibration sensation and proprioception. What is the postcentral gyrus? The postcentral … Postcentral Gyrus: Structure, Function & Diseases
The praecentral gyrus is a part of the brain and is home to the primary motor cortex, which is interconnected with central motor neurons and the pyramidal tracts. The area of the brain is considered the center of movement control. In lesions, irreversible movement disorders, spasticity, or paralysis often occur. What is the praecentral gyrus? … Praecentral Gyrus: Structure, Function & Diseases
Synonyms Neocortex, Isocortex Definition The neocortex represents the youngest part of the brain in terms of evolutionary history. It can be subdivided into four lobes, which take over different brain functions. Frontal lobe Anatomy & Function: The frontal lobe plays the central role in the initiation of motor function. In the motocortex (gyrus precentralis) the … Neocortex
Occipital lobe Anatomy & Function: In the occipital lobe, which is located in the posterior fossa above the cerebellum, lies the visual center, i.e. part of the visual system. The information comes from the retina via the optic nerve (2nd cranial nerve) into the optic chiasm (optic nerve crossing), where the information of the outer … Occipital lobe | Neocortex
