Chapter 8- Nervous Systems

Question 1

What is the CNS?

Answer 1

The central nervous System that consists of the brain and spinal cord

Question 2

What is PNS?

Answer 2

Peripheral nervous system this is the four pairs of cranial nerves and 31 pairs of spinal nerves

Question 3

What is ANS?

Answer 3

Automatic nervous system a subdivision of PNS which controls the motor functions of the internal organs

Question 4

What is a cell body?

Answer 4

Hey so body contains the nucleus and most of the cytoplasm

Question 5

What is a dendrite?

Answer 5

The process dessins the airport towards the cell body

Question 6

What is a axon?

Answer 6

The process that says impulses away from the cell body

Question 7

What is Neurilemma?

Answer 7

I think covering along the action that is external to the myelin which is present for most regeneration of the axon

Question 8

Sensory (afferent)

Answer 8

Send signals towards the central nervous system it has long dendrites and a short axon

Question 9

Motor (efferent)

Answer 9

Sends signals away from the central nervous system and has short dendrites or the dendrite maybe absent in the action as long

Question 10

Interneuron

Answer 10

Found between sensory and motor units which is contained within the central nervous system

Question 11

What is the histology of neuroglia?

Answer 11

Support regulation and protection of neurons

Question 12

Myelinated axon

Answer 12

Transmit ACH potential faster

Question 13

Ventricles?

Answer 13

HAs 4 hollow spaces within the brain

Question 14

What is the CSF?

Answer 14

Cerebrospinal fluid which is on the outside of the spine

Question 15

Histology of neural tissue?

Answer 15

Neurons for processing transferring and storage of information

Neuroglia for support regulation and protection of neurons

Question 16

What is the synaptic transmission?

Answer 16

A neuron develops in action potential

The action potential triggers the release of neurotransmitters such as acetylcholine

The neurotransmitter excites the next sale located on the other side of the synapse

Sorry I’m begins to diffusing to the postsynaptic cell starting the development of its action potential

The neurotransmitter is broken down for transportation away from the synapse

Question 17

What is a receptor?

Answer 17

A group of cells that detects a stimulus example during a knee-jerk patellar reflex

Question 18

What is the sensory neuron?

Answer 18

Since impulses from one point of the stimulus to the central nervous system also known as CNS

Question 19

Interneuron?

Answer 19

The central nervous system that since impulses from one sensory neuron to the motor neuron

Question 20

What is the motor neuron?

Answer 20

The neuron that says imposes to the a factor for spinal cord reflexes

Question 21

What are reflexes?

Answer 21

An automatic response that depends on the activation of the components of the reflex arc

Question 22

What are the components of the reflex arc?

Answer 22

Receptor, sensory neuron, interneuron, motor neuron, effector , reflexes
