Answer 1

1. Motor (efferent)
2. Interneurons
3. Sensory (afferent)

Question 2

What does the parasympathetic branch of the autonomic nervous system focus on?

Answer 2

“Rest-and-digest”

Question 3

What are some of the characteristic traits of the parasympathetic branch?

Answer 3

• Constricts pupils
• Stimulates flow of saliva
• Constricts bronchi
• Slows heart rate
• Stimulates peristalsis and secretion
• Stimulates bile release
• Contracts bladder

Question 4

What is the sympathetic branch focused on?

Answer 4

“Flight-or-fight” responses

Question 5

What are some of the characteristic traits of the sympathetic branch?

Answer 5

Dilates pupils
Inhibits salivation 
Relaxes bronchi
Accelerates heartbeat 
Piloerection or sweating 
Inhibits peristalsis and secretion 
Stimulates glucose production and release
Secretion of adrenaline and noradrenaline 
Inhibits bladder contraction 
Stimulates orgasm

Question 6

What does the hindbrain contain?

Answer 6

Contains the cerebellum, medulla oblongata, and reticular formation

Question 7

What does the midbrain contain?

Answer 7

Contains the inferior and superior colliculi

Question 8

What does the forebrain contain?

Answer 8

Contains the thalamus, hypothalamus, basal ganglia, limbic system, and cerebral cortex

Question 9

What does the thalamus do? What part of the brain is it located in?

Answer 9

Located in the forebrain.

Relay station for sensory information

Question 10

What does the hypothalamus do? What part of the brain is it located in?

Answer 10

Located in the forebrain.
Maintains homeostasis and integrates with he endocrine system through the hypophyseal portal system that connects it to the anterior pituitary

Question 11

What does the basal ganglia do? What part of the brain is it located in?

Answer 11

Located in the forebrain.

Smoothens movements and helps maintain postural stability

Question 12

What do the limbic system do? What part of the brain is it located in?

Answer 12

Located in the forebrain.
Controls emotion and memory. Includes septal nuclei (pleasure-seeking), amygdala (fear and aggression), hippocampus (memory), and fornix (communication within limbic system)

Question 13

What are the septal nuclei associated with?

Answer 13

Pleasure-seeking

Question 14

What is the amygdala associated with?

Answer 14

Fear and aggression

Question 15

What is the hippocampus associated with?

Answer 15

Memory

Question 16

What is the fornix associated with?

Answer 16

Communication within the limbic system

Question 17

What are the lobes that the cerebral cortex is divided into?

Answer 17

Frontal
Parietal
Occipital
Temporal

Question 18

What does the frontal cortex do?

Answer 18

Frontal cortex is a lobe of the cerebral cortex.
Involved in executive function, impulse control, long-term planning (prefrontal cortex), motor function (primary motor cortex), speech production (Broca’s area)
