All terms in this list:

neurology: The branch of medicine that deals with the disorders of nervous system.

nerve fibres: a threadlike extension of a nerve cell and consists of an axon and myelin sheath (if existence) in the nervous system.

brain stem: The part of the brain that connects the spinal cord to the forebrain and cerebrum.

pons: A bridge-like tissue connecting two parts of an organ

forebrain: The anterior part of the brain, including the cerebrum, thalamus, and hypothalamus.

hindbrain: The posterior part of the brain, comprising the cerebellum, pons and medulla

medulla: The soft inner part of something, especially the pith of a fruit.

cerebellum: Part of the hindbrain in vertebrates. It plays an important role in sensory perception, motor output, balance and posture.

cerebrum: In humans it is the largest part of the brain and is the seat of motor and sensory functions, and the higher mental functions such as consciousness, thought, reason, emotion, and memory.

central nervous system: In vertebrates, that part of the nervous system comprising the brain, brainstem and spinal cord.

thalamus: Either of two large, ovoid structures of grey matter within the forebrain that relay sensory impulses to the cerebral cortex.

cranial nerve: Any of the twelve paired nerves that originate from the brainstem instead of the spinal cord.

meninx: a membrane, especially one of the three membranes enclosing the brain and spinal cord in vertebrates

cerebral: Intellectual rather than emotional.

cerebral cortex: The grey, folded, outermost layer of the cerebrum that is responsible for higher brain processes such as sensation, voluntary muscle movement, thought, reasoning, and memory.

optic nerve: Either of a pair of nerves that carry visual information from the retina to the brain

oculomotor nerve: The third of twelve paired cranial nerves, which controls most of the eye's movements and constriction of the pupil and maintains an open eyelid.

trochlear nerve: A motor nerve that innervates the superior oblique muscle of the eye.

meninges: The three membranes that envelop the brain and spinal cord.

medulla spinalis: spinal cord

medulla oblongata: The lower portion of the brainstem.

trigeminal nerve: The nerve responsible for sensation and motor function in the face and mouth.

facial nerve: The seventh (VII) of twelve paired cranial nerves.

cochlea: The complex, spirally coiled, tapered cavity of the inner ear in which sound vibrations are converted into nerve impulses.

vagus nerve: Either of the tenth pair of cranial nerves, which extends from the brainstem down into the abdomen. Branches of these important nerves supply the tongue, larynx, lungs, gut, and heart.
