Question 1

What is the hypothalamus?

Answer 1

controls pituitary gland and links the nervous system to the endocrine system

Question 2

What are hormones and how are they produced?

Answer 2

Chemical messengers produced by endocrine glands

Question 3

What is the pituitary gland?

Answer 3

Endocrine gland at the base of the brain that secretes hormones that affects other glands. Growth and development

Question 4

Adrenal gland?

Answer 4

Pair of endocrine glands that are involved in the human stress response

Question 5

What is the endocrine system?

Answer 5

System of glands that supplement the nervous system by secreting hormones into the bloodstream

Question 6

How does the hypothalamus connect to the endocrine system?

Answer 6

The hypothalamus receives neural imput from the brain and triggers a hormone release in the pituitary gland

Question 7

What is structural plasticity?

Answer 7

The ability to change the brains physical structure in response to learning, practice, or environmental influences

Question 8

What is functional plasticity?

Answer 8

Brains ability to shift functions from a damaged area to an un damaged area.

Question 9

What is neurogenesis?

Answer 9

The development of new neurons

Question 10

What is cortical localization?

Answer 10

Certain functions are located throughout certain areas of the brain.

Question 11

What is lateralization of function?

Answer 11

Certain cognitive functions processed on one side of the brain

Question 12

What are Broca and Wernicke’s areas, and what did they show about our left hemisphere of the brain?

Answer 12

Language and speech are lateralized on the left hemisphere of the brain, which were shown to be involved in language production and reception

Question 13

What is aphasia?

Answer 13

Loss of ability to speak or understand language

Question 14

Why is the brain called an integrated system?

Answer 14

Simple behaviors require highly integrated interaction of trillions of synapses

Question 15

What have researchers found with rats and neurogenesis in article of 81-83?

Answer 15

Enriched environments and exercise increase the rate of neurogenesis. Increase blood flow to hippocampus

Question 16

What is the nervous system?

Answer 16

Primary communication network. Divided into central nervous system and peripheral nervous system

Question 17

What are nerves made of?

Answer 17

Neurons bound together by connective tissue

Question 18

What is the central nervous system made of?

Answer 18

The brain and spinal chord

Question 19

Occipital lobe?

Answer 19

Area back of each hemisphere of the brain that is primary receiving area for visual information

Question 20

Parietal lobe?

Answer 20

Area on each hemisphere above the temporal lobes that process somatic information (touch, temperature)

Question 21

Temporal lobe?

Answer 21

Area on each hemisphere near the temples that is primary receiving for auditory information.

Question 22

Frontal lobe?

Answer 22

Largest lobe of each cerebral hemisphere that processes muscle movements and involved in thinking, planning, and emotional control

Question 23

Corpus callosum?

Answer 23

Thick band of axons that connects the left and right hemispheres and acts as a communication link between them.

Question 24

What is the cerebellum?

Answer 24

Two sided hindbrain structure, responsible for muscle coordination and maintaining posture

Question 25

What’s the brain stem?

Answer 25

Hindbrain and the midbrain that connects the base of the brain and spinal chord, responsible for visual and auditory info

Question 26

What is the cortex of are brain, what do it looks like, what connects to hemispheres?

Answer 26

The cortex= cerebellum, looks sponge

Corpus callosum connects the hemispheres

Question 27

What are the branches of our nervous system and what are their functions?

Answer 27

Central nervous system- brain and spinal cord
Peripheral Ns- receives and sends messages to central nervous system.
Somatic NS- control of digestive skeletal muscle, lifting ur hand.
Autonomic NS- controls gland, heart, automatic pilot.
Sympathetic NS-arouses, expends energy, raised heart beat and blood pressure.
Parasympathetic NS- conserve energy, calms you, slows heart, cools u.

Question 28

What does the somatic NS do?

Answer 28

Communicates sensory info to the CNS and carries motor messages from CNS to the muscles

Question 29

What does the autonomic NS do?

Answer 29

Regulates involuntary action, breathing, digesting,
