OSPE 1

Question 1

Midbrain Function

Answer 1

Most rostral structure of brainstem. Connects “hindbrain” (pons, medulla, and cerebellum) with “forebrain” (cortex) via cerebral peduncles. Has superior and interior colliculi.

Question 2

Pons Function

Answer 2

Relay system between spinal cord, cerebellum & cerebrum. Transmit between structures via cerebellar peduncles. Passageway for spinal cord tracts.

Question 3

Medulla Oblongata Function

Answer 3

Continuous with spinal cord. Anterior is motor. Posterior is sensory.

Passageway for motor/sensory neurons

Autonomic control

Breathing regulation

Question 4

Cerebellum Function

Answer 4

The little brain. Coordination of voluntary movement. Compares planned movement with actual movement. Monitors & makes adjustments to correct motor plans.

Question 5

Thalamus function

Answer 5

Collection of nuclei (sensory & motor). Gatekeeper for sensory and motor signals that need to get to cerebral cortex (all sensory except olfaction).

Question 6

Hypothalamus function

Answer 6

Maintain homeostasis by controlling endocrine and autonomic function.
