Unit 2: Part 1D: Parts in the Hindbrain

Question 1

Brainstem

Answer 1

begins where the spinal cord swells as it enters the skull; responsible for autonomic survival functions

Question 2

Medulla

Answer 2

controls basic life functions; base of brainstem; controls heartbeat, breathing, circulation, and swallowing; injury to this area usually leads to death

Question 3

Reticular Formation

Answer 3

nerve network of the brainstem which controls arousal and wakefulness; modulates muscle reflexes, breathing, and pain perception; injury usually leads to coma

Question 4

Pons

Answer 4

has a bridge of fibers that connects brainstem to cerebellum; involved in sleep and arousal, coordinating movements

Question 5

Cerebellum

Answer 5

“little brain”; controls voluntary movements and balance; responsible for muscle memory (walking, riding a bike); injury leads to a loss in coordination

Question 6

Thalamus

Answer 6

sensory switchboard of the brain; directs messages to correct areas of the brain; located at the top of the brain stem in the center of your brain; deals with all senses except smell
