Biopsychology

Question 1

3 types of neurons

Answer 1

Motor _ CNS to effectors muscles and glands
Sensory - PNS to CNS
Relay - connect sensory to motor or other relay neurons

Question 2

The structure of a neuron

Answer 2

Cell body -> includes nucleus (genetic material)
Dendrites off the cell body (nerve impulses to neurons)
Axons carries impulses away from cell body
Myelin sheath (protective layer speeds up transmission)
Nodes of ranvier are gaps along myelin sheath that speeds up
Terminal buttons (communicate with next neurons)

Question 3

Electric Transmission

Answer 3

Neuron inside the cell is negatively charged. When activated by a stimulus it becomes positively charged causing an ACTION POTENTIAL
This creates an electrical impulse that travels down the axon towards the end of the neuron

Question 4

Synaptic Transmission - Chemical transmission

Answer 4

Neural networks - groups of neurons

Each neuron is separated by a synapse
