Biopsychology (copy)

SNS transmits

________ info from sensory receptors to the CNS and info from the brain to muscles to produce movements.

Adrenaline

________ is released from the adrenal gland which triggers physiological changes in the body to prepare for fight or flight.

Inhibition

________- when the neurotransmitter decreases the positive charge making git less likely to fire.

Signals

________ between neurones are transmitted chemically across the synapse.

Hormones

________ are biomedical substances that circulate in the blood but only effect target organs.

network of cells

A(n) ________ in the human body that is our primary internal communication sytem.

Excitation

________- when a neurotransmitter releases a positive charge of the postsynaptic neurone.

summation

Summation- whether or not the postsynaptic neurone fires the message due to the total charge of the signal.

electrical charge

When faced with a stimulus the neurones is actively charged causing action potential, which pushes and ________ down the axon, to the end of the neurone.

Relay neurones

________ have short dendrites and short axons.

pituitary gland

master gland that controls all the glands

neurotransmitter

The ________ is then released and diffuses across the synapse binding to the receptor site on the dendrite of the next neurone.

chemical signal

The dendrite then converts the ________ into an electrical signal.

Sensory neurones

________ are in the PNS in clusters called ganglia.

hormones

chemical signals produced by glands

3 types of neurones

sensory, motor and relay
