Functions of Brain Structures and Spinal Cord

Question 1

Cerebrum (cerebral hemispheres)

Answer 1

Serves higher mental functions (cognition, language, and memory); integrates sensorimotor functions and perceptual experiences

Question 2

Limbic lobe

Answer 2

Regulates motivational and emotional states

Question 3

Basal ganglia

Answer 3

Regulates motor movements and muscle tone

Question 4

Thalamus

Answer 4

Channels sensorimotor information to cortex; participates in cortex-mediated functions; regulates crude awareness of sensation

Question 5

Hypothalamus

Answer 5

Regulates body temperature, food intake, water balance, hormonal secretions, emotional behavior, and sexual responses; controls the activities of autonomic nervous system

Question 6

Cerebellum

Answer 6

Participates in the coordination of skilled movements and regulation of equilibrium

Question 7

Midbrain

Answer 7

Mediates auditory and visual reflexes; regulates cortical arousal; houses cranial nerve nuclei

Question 8

Pons

Answer 8

Contains cranial nerve nuclei and sensory motor-regulating fibers

Question 9

Medulla

Answer 9

Contains cranial nerve nuclei; regulates respiration, phonation, heartbeat, and blood pressure

Question 10

Spinal cord

Answer 10

Links body with central nervous system; regulates reflexes
