Brain Physiology
The glandular portion of this structure is responsible for secreting melatonin.
What is the epithalamus?
Sense of hearing and equilibrium.
What is CNVIII Vestibulocochlear?
The most inferior region of the brainstem.
What is the medulla oblongata?
The two main divisions of the peripheral nervous system.
What are the somatic and autonomic nervous systems?
Sensory receptors that detect light striking the eye.
What are photoreceptors?
The master endocrine gland. Our main regulator of homeostasis.
What is the hypothalamus?
Motor supply to trapezius and sternocleidomastoid.
What is CNXI Accessory (Spinal)?
The name for the shallow grooves between the folds in the cerebrum.
What are sulci?
The thoracolumbar division of the ANS is also known as this division.
What is the sympathetic nervous system?
The names of the three auditory ossicles, which are controlled by tiny skeletal muscles.
What are the malleus, incus and stapes?
A bridge between the cerebellum and cerebrum, which relays motor information.
What is the pons?
In the parasympathetic state, stimulates tear, nasal and salivary glands.
What is CNVII Facial?
The location of grey matter in the cerebrum.
What is the cerebral cortex?
The effect of the sympathetic nervous system on the abdominal viscera arterioles.
What is constriction?
The conscious or subconscious awareness of change in the environment.
What is sensation?
This structure is the "gateway" to the cerebral cortex, relaying sensory and motor information.
What is the thalamus?
Lateral eye movement.
What is CNVI Abducens?
The outer layer of the dura mater in the brain.
What is the periosteal layer?
This neuron releases the neurotransmitter norepinephrine (NorEpi).
What is the postganglionic sympathetic neuron?
This structure is the exact centre of the retina; contains the highest concentration of cones and is the area of highest visual acuity.
What is the fovea centralis?
This structure maintains consciousness and awakening from sleep.
What is the reticular formation?
Sensory role in taste (gustation) and motor role in swallowing.
What are CNIX Glossopharyngeal and CNX Vagus?
These structures produce cerebrospinal fluid.
What are the choroid plexuses (capillaries in the ventricle walls, which are covered by ependymal cells)?
The parasympathetic preganglionic neurons arise from these two areas (be specific).
What are CN's III, VII, IX, X and lateral grey horns of S2-4?
The clear, jelly-like substance contained in the posterior chamber of the eye.
What is the vitreous body?
