Q

what are the characteristics of a interior surface of a resting neurons plasma membrane potential

A

negative charge and contain less sodium than outside the cell

18
Q

characteristics of graded potentials

A

called postsynaptic potentials Can form on receptor endings and are Short-lived

19
Q

When an excitatory postsynaptic potential (EPSP) is generated on the dendritic membrane what happens

A

a single type of channel will open, permitting flow of sodium and potassium simultaneously

20
Q

inhibitory postsynaptic potential (IPSP) is associated with what?

A

hyperpolarization

21
Q

what are Schwann cells in the PNS similar to

A

oligodendrocytes in the CNS

22
Q

what does the synaptic cleft use action potentials for?

A

to transmit a chemical signal to the post synaptic cell.

23
Q

what is an interneuron

A

a neurons whos primary job is to connect other neurons

24
Q

what does the Central nervous system contain ?

A

the spinal cord and brain

25
Q

what are the functions of the autonomic nervous system (involuntary)

A

Innervation of cardiac muscle
Innervation of smooth muscle in the digestive tract
Innervation of glands

26
Q

what would happen in the event or Loss of the enzyme acetylcholinestera

A

result in inability to destroy and remove acetylcholine from the synaptic cleft

27
Q

Voltage-gated channels open in response to what

A

to a change in membrane potential and participate in generation and in conduction of action potentials

28
Q

what are some characteristics of neurons

A

High metabolic rate
Conduct impulses
Extreme longevity
