Neuroscience Pop Quiz/Exam 1 Review (Anatomy of the Nervous System - Mesencephalon)

Proprioception

\-Recognizing position of body parts

\-Recognizes the shape in your hand to identify the type of shape you are holding

Spinothalamic Tract

Contains sensory fibers that transmit the sensations of pain and temperature

Dorsal Column-Medial Lemniscus Tract

An ascending pathway in the spinal cord that relays signals from touch and proprioception

Cerebral Aqueduct

Doorway connecting the 3rd ventricle to the 4th ventricle

What are the structures associated with the midbrain?

\-Superior and inferior colliculus

\-Cerebral peduncle

\-Reticular formation

\-Cerebral aqueduct

What are the 2 cranial nerves involved in the mesencephalon?

\-Cranial nerve III (Oculomotor)

\-Cranial nerve IV (Trochlear)

What cranial nerve exits on the ventral surface of the midbrain?

Cranial nerve III

Superior Colliculus

Helps us to attend to new visual stimuli

Inferior Colliculus

Helps us to attend to new auditory stimuli

Oculomotor Nerve (cranial nerve III)

Moves the eyes; controls 4/6 eye muscles

Is the red nucleus motor or sensory?

Motor

Trochlear Nerve (cranial nerve IV)

Moves the eyes
