Neurophysiology — Flashcards

Flashcard 81: The _____ of the reticular formation is responsible for synthesis of serotonin

Answer: raphe nucleus

Flashcard 82: In the indirect basal ganglia pathway, the neurons of the subthalamic nucleus lead to _____ of neurons of the globus pallidus internus

Answer: excitation

Flashcard 83: The _____ is responsible for synthesis of the neurotransmitter GABA

Answer: nucleus accumbens

Flashcard 84: Autonomics _____ acetylcholine receptors are found on autonomic ganglia

Answer: Nicotinic

Flashcard 85: Injury to the brainstem or the spinal cord above the _____ level can be rapidly fatal due to the disruption of cardiorespiratory regulation and diaphragmatic function.

Answer: C4

Extra: The phrenic nerve (C3-C5) innervates the diaphragm ("C3, 4, 5 keep the diaphragm alive"). Injuries above the C4 level lead to respiratory paralysis. Brainstem (medullary) injuries can damage the vital respiratory and cardiovascular centers.

Flashcard 86: The _____, also known as the vomiting center (located in the medulla) receives main inputs from: 1. GI tract 2. Vestibular system 3. Area postrema (chemoreceptor trigger zone)

Answer: nucleus tractus solitarius

Flashcard 87: Inhibition of _____ proteins inhibits docking of neurotransmitter vesicles and ultimately neurotransmitter release

Answer: SNARE

Flashcard 88: The neurogenic symptoms of hypoglycemia are caused by _____ activation and are mediated via neurotransmitters from sympathetic postganglionic nerve fibers

Answer: sympathoadrenal

Flashcard 89: The _____nergic neurons in anterior hypothalamus and adjacent forebrain regions, on stimulation, induce sleep.

Answer: GABA-

Flashcard 90: Procedural/Skills memory (Nondeclarative) is stored in _____, cerebellum and motor cortex

Answer: striatum
