What are the two main divisions of the nervous system?

Central Nervous System
Peripheral Nervous System

1

What is the Central Nervous System made up of? What is its function?

Brain and Spinal Cord
Process thoughts, feelings

2

What is the Peripheral Nervous System made up of? What is its function?

Nerves and neurons in spinal cord and brain
Communicate with eyes, skin, ears, mouth, control muscles and glands

3

What are the divisions of the peripheral Nervous system? What are their functions?

Somatic Nervous System: Sensory and voluntary movements
Autonomic Nervous System:Controls everything the Somatic doesn't, emotions, stress, health

4

What are the divisions of the Autonomic System? What are their functions?

Sympathetic:Handle stress, fight or flight
Parasympathetic:Restore body to normal function

5

The flight or fight response is a part of what branch of the nervous system? What is the purpose of this response?

Sympathetic

6

What is the resting potential of a neuron?

When neuron is waiting for the next action potential

7

What is the refractory period? What occurs during this period?

Recharging period
Unable to fire

8

What are the parts of the neuron? What are the functions of each?

Dendrite:Receive information from other neuron
Soma:Body of neuron, keeps nucleus and cell healthy
Axon:Make cell longer and carry messages to axon terminal
Axon terminal:Release chemicals to carry message to next dendrite

9

What is the point of communication between neurons?

Synapse

10

How do neurons communicate? Which of these is the most common?

Electrically and chemically
Chemically

11

What are hormones? What do they do?

No idea

12

What are the basic types of neurons? What do each of them do?

Sensory, motor, inter

13

What are neurotransmitters?

Carry messages, each has a distinct shape chemically

14

What is action potential?

Triggered by chemical signals

15

What is the limbic system? What makes up the limbic system?

Amygdala, hippocampus, hypothalamus, thalamus

16

What are the functions of the hypothalamus? Where is it located?

Regulates body temperature, hunger
Below thalamus

17

What are the 4 lobes of the brain? What are the primary functions of each?

Frontal:Judgement, creativity, problem solving, planning
Parietal:High sensory and language function
Occipital:Vision
Temporal: Hearing, memory, meaning of language

18

What is the name of the German neurologist that identified an area on there left temporal lobe responsible for the ability to understand spoken language?

Carl Wernicke

19

What is the Broca's area? What is the wernicke's area? What is the location of each?

Muscles involved with speech, left frontal love
Meaning from words, left temporal lobe

20

The left hemisphere is known for? The right hemisphere is known for?

Logic
Imagination

21

What is the Amygdala? What does it do? Where is it located?

Emotions
Back of thalamus

22

What is the hippocampus? What does it do? Where is it located?

Memorizing
Cerebrum, temporal lobe

23

What is the pituitary gland? What does it do? Where is it located?

Secretes hormones, controls other glands
Attached near base of brain

24

What are the 3 parts of the brain?

Cerebrum, cerebellum, brain stem

25

What does the corpus Callosum do?

Connects the left and right hemispheres

26

What are fissures? What are the types? Where are they?

Longitudinal:Divides two hemispheres
Transverse:Separates cerebrum from cerebellum
Lateral:Divide temporal from frontal and parietal

27

What is the cerebellum? What does it do? Where is it located?

Controls balance, coordination,
Below back of brain
