Physiology Lecture Practice Test 2 Review

Vocabulary flashcards based on the Physiology Lecture Practice Test 2 answer key covering key terms in neuroanatomy, sensory systems, and cellular physiology.

Cerebellum

The part of the brain that coordinates voluntary movements such as posture resulting in smooth and balanced muscular, motor activity.

Superior Colliculi

Structure on the brain stem associated with visual reflex.

Abducens Nerve (CN VI)

The cranial nerve responsible for motor function such as movement of the eyes laterally.

Ependymal Cells

Cells that secrete cerebrospinal fluid.

Tufted and Mitral Cells

Cells that form the axons of the olfactory cranial nerve sending information to the brain.

Superior Oblique

Muscle that regulates the downward and outward movement of the eye.

G-Coupled Protein Receptors (Gustatory)

Receptors used by umami and bitter molecules to depolarize gustatory cells.

IP3 and cAMP

Secondary messenger chemicals used by metabotropic receptors in gustatory physiology.

Endolymph

Fluid found in the scala media of the cochlea that is rich in $\text{K}^+$ ions.

L Cones

Photoreceptors that absorb long wavelengths of light in the retina that help you see color.

Adrenergic Receptors

Receptors at target tissues that bind to catecholamines.

Proprioceptors

Receptors that detect change in muscle length.

Microglial Cells

Neuroglial cells that destroy pathogens in the central nervous system as a part of the immune system.

Temporal Lobe

Part of the cerebral cortex that processes hearing.

Occipital Lobe

Part of the brain associated with vision.

Free Nerve Endings

A type of non-encapsulated sensory receptor.
