The Human Animal

Question 0

Dendrites

Answer 0

Branch extension of a neuron that receives incoming messages

Question 1

Corpus callosum

Answer 1

A bundle of nerve fibers that make communication possible between both hemispheres of the brain

Question 2

Axon

Answer 2

The other Branchy end of the neuron that sends outgoing messages

Question 3

Nervous system

Answer 3

The brain and body’s network of neurons coordinates all internal body functions and body’s response to external stimuli

Question 4

Stimulus

Answer 4

Incoming information that causes the body to respond

Question 5

Synapse

Answer 5

Space or gaps that separates neurons

Question 6

Neurotransmitter

Answer 6

Chemicals that act as messengers that transmit the signal across the gap between neurons across (the synapse)

Question 7

Reflex arc

Answer 7

A pathway that Messages travel back to muscles in your arms. A signal pathway that goes from sensory neuron to spinal cord to motor neuron day passing the brain to keep us safe

Question 8

What are the two parts of the central nervous system?

Answer 8

The two parts of the central nervous system are the brain and the spinal cord

Question 9

What are the characteristics of the human hand?

Answer 9

Strong precise grasp, flexible, long thumb, opposable thumb

Question 10

What is a power grip?

Answer 10

Grasping objects with palm and curl fingers around can apply pressure to the whole hand

Question 11

What is a Percision grip?

Answer 11

A more intricate grab that requires a specific alignment of the thumb with one or more fingers some applies pressure against another finger or fingers in order to accomplish a precise motion (ex: picking up a coin)

Question 12

What does the cerebrum control?

Answer 12

Learning, memory, language, speech, voluntary body movements, sensory perception (higher thinking)

Question 13

What does the cerebellum control?

Answer 13

Balance, posture, and coordination

Question 14

What does the brainstem control?

Answer 14

Breathing rate, heart rate, and blood pressure. Considered the most primitive part of the brain, responsible for support systems.

Question 15

What part of the brain would you expect to be very small in primitive organisms?

Answer 15

I would expect the cerebrum to be very small in primitive organisms

Question 16

What does a neurobiologist do?

Answer 16

Studies different regions of the brain and works to learn more about how they function in with the control (studies the nervous system)

Question 17

What does the motor cortex do?

Answer 17

Iit controls the movement of your body

Question 18

What does the sensory cortex do?

Answer 18

It lets you feel sensations from your body

Question 19

What does the corpus callosum do?

Answer 19

It makes communications possible between both hemispheres of the brain (connects right and left hemispheres)

Question 20

What are the parts of a neuron and what does each do?

Answer 20

• Dendrite: acts like an antenna to receive incoming messages
• Axon: sends outgoing messages
• Cell body: contains nucleus

Question 21

Explain how Messages move from neuron to neuron

Answer 21

• Electrical signal is turn from electrical energy to chemical energy neurotransmitter at the end of the axon
• neurotransmitter crosses the synapse -the narrow transmitter is change from chemical energy back into electrical energy at the dendrites of the next cell

Question 22

Explain the functioning of a reflex arc

Answer 22

It’s a signal from sensory neurons the spinal cord to motor neuron that bypasses the brain (for speed) to keep us safe fast

Question 23

What are the criteria for a testable question?

Answer 23

A question that can be tested by an experiment and gathering concrete did not just an opinion has to describe a test that you can actually do

Question 24

What does the left hemisphere control?

Answer 24

Language and speech, as well as mathematics, and other analytical abilities and the right side of the body

Question 25

What does the right hemisphere control?

Answer 25

Visual and spatial processing and the left side of the body

Question 26

How do you brands of higher and lower primates differ?

Answer 26

Brains of how your primates tend to have a bigger cerebrum and more wrinkles on the brain than lower primates

Question 27

What does the peripheral nervous system include?

Answer 27

Transmits information between the central nervous system and the rest of the body (somatic and autonomic)

Question 28

What is the somatic nervous system responsible for?

Answer 28

It connects the central nervous system to the skeletal muscles (requires thought)

Question 29

What is the autonomic nervous system responsible for?

Answer 29

It connects the central nervous system to the heart and other internal organs (takes information from internal organs to the brain, happens automatically)

Question 30

Describe the pathway of a reflex arc

Answer 30

Nerve pathway that consist of a sensory neuron carrying a signal to an Internet which sends a signal to a motor neurons by passing the brain
