Transcranial Magnetic Stimulation

Question 11

What is a neuron? (2)

Answer 11

The basic unit of the nervous system (nerve cells)

Transmit electrical I,pulses

Question 12

what is the structure of a neuron? (3)

Answer 12

Cell body
Dendrite (receptive cells)
Axons (transmitting extension)

Question 13

What is the neuron doctrine?

Answer 13

Concept that the nervous system is made up of discrete individual cells
- proposed Ramon y Cajal

Question 14

What is an axon? (2)

Answer 14

A single extension from the nerve cell That carries action potentials From the fell body to other neurons
Called the conduction zone because it absorbs all info and relays it to other parts of the body

Question 15

what is a dendrite?

Answer 15

One of the extensions of the cell body That are the receptive services of the neurons

Question 16

What is a synapse?

Answer 16

the tiny gap between neurons where information is passed from one to another

what are the components of a synapse? (3)

Answer 18

• the presynaptic ending
• the synaptic cleft
• the postsynaptic ending

Question 19

What does the presynaptic ending contain?

Answer 19

neurotransmitters

Question 20

Where is the synaptic cleft?

Answer 20

between the 2 nerve cells

Question 21

what does the postsynaptic ending contain?

Answer 21

receptor sites

Question 22

What are the 3 types of neurons?

Answer 22

-sensory
-motor
Inter

Question 23

What does the sensory neuron do?

Answer 23

Carries info from the body to the spinal cord and the brain

Question 24
