Nervous System

Question 1

It is involved in receiving information about the environment around us and generating responses to that information and coordinating the system

Answer 1

Nervous System

Question 2

The main processing center for the entire nervous system. It consists two main components, the brain and spinal cord

Answer 2

Central Nervous System (CNS)

Question 3

Answer 3

Brain

Question 4

Serves as a channel for signals between the brain and the rest of the body, and controls simple muscolosketal reflexes without input to from the brain

Answer 4

Spinal Cord

Question 5

It connects the central nervous system to the organs and limbs and it has two main division, the spinal nerves and cranial nerves

Answer 5

Peripheral Nervous System (PNS)

Question 6

Answer 6

Spinal Nerve

Question 7

The nerve fibers that carry information into and out of the brain stem

Answer 7

Cranial Nerve

Question 8

Is is activated when the body is in a dynamic role or stress

Answer 8

Question 9

Maintains body functions and restores the body to normal or relaxed mode

Answer 9

Parasympathetic

Question 10

Answer 10

Sensation, Integration, and Response

Question 11

Refers to receiving information (stimuli/stimulus) about the environment, either what is happening outside or inside the body

Answer 11

Sensation

Question 12

Refers to anything that causes a response

Answer 12

Stimuli

Question 13

Received by sensory structures are communicated to the nervous system where that information is processed

Answer 13

Integration

Question 14

The nervous system produces a response in effector organs (such as muscles or glands) due the sensory stimuli

Answer 14

Response

Question 15

Answer 17

Parietal Lobe

Question 18

Responsible for vision

Answer 18

Occipital Lobe

Question 19

Responsible for speech, hearing and memory

Answer 19

Question 20

It controls posture, balance and the fine muscle movements

Answer 20

Cerebellum

Question 21

It controls bodily functions like breathing, circulation and sleep, it is located in the bottom part of the brain and connects the cerebrum to the spinal cord

Answer 21

Brain Stem

Question 22

Specialized cells that transmit messages to and from the brain and spinal cord thought-out the body

Answer 22

Nerve Cell

Question 23

Receives the signals from other neurons or from the body and pass those messages along the cell body

Answer 23

Dendrites

Question 24

Maintains structure of the neuron and provides energy or electrical signals

Answer 24

Cell body

Question 25

Specialized organelles, synthesize proteins in a neuron

Answer 25

Nucleus

Question 26

Where electrical impulses from the neuron travel away to be received by other neurons

Answer 26

Axon

Question 27

They are typically the sites where synapse with other neurons are found

Answer 27

Axon terminal

Question 28

Point of contact between neurons where the information or message is passed

Answer 28

Synapses

Question 29

Protective layer around some axons and helps to speed up the signal messages

Answer 29

Myelin Sheath

Question 30

Contains Na+ and K+ channels, allowing action potential to travel quickly down the axon by jumping one node to next

Answer 30

Nodes of Ranvier

Question 31

Its role is for the development, supplying nutrients and regeneration of peripheral nerves

Answer 31

Schwann Cell

Question 32

The system associated with the voluntary control of body movements

Answer 32

Property of a human biological systems where the self-regulating process tends to maintain the balance for the survival

Answer 35

Homeostasis

Question 36

System that respond to changes, occur in the body

Answer 36
