Question 2

What does Inhibitory function mean?

Answer 2

act like a “brake” in the brain, slowing things down to keep everything in check

Question 3

What is action potential?

Answer 3

an action potential is the electrical pulse that carries messages between neurons

Question 4

What does excitatory function mean?

Answer 4

act like a “gas pedal,” speeding up brain and nervous system activity, which can lead to things like muscle movement, thinking, or sensations like touch or pain.

Question 5

Which last’s longer Hormones or Neurotransmitters? WHY!

Answer 5

Hormones last longer because it takes a bit longer to go through the body compared to Neurotransmitters

Question 6

What does Efferent neuron do? And another name for it?

Answer 6

It can be referred to as Motor nueron.
It is a nerve cell in your PNS that transmits impulses from sensory or inter neurons to muscle cells that contract or gland cells that secrete.

Question 7

What does Afferent Neuron do? And another name for it?

Answer 7

It can also be referred to as the Sensory Neuron.
It is a nerve cell in your PNS that transmits impulses from receptors to the brain or spinal chord.

Question 8

What is the Endocrine system?

Answer 8

Ductless glands that typically secrete hormones directly into the blood, which help regulate body and behavioral processes.

Question 9

What is the ALL OR NOTHING PRINCIPLE?

Answer 9

The law that the neuron either generates an action potential when the stimulation reaches a threshold or doesn’t fire when stimulation Is below threshold. The strength of the action potential is constant where it occurs.

Question 10

What are Neurotransmitters?

Answer 10

It is chemical messages that is released by the axon terminal of the presynaptic neuron into the synapse.
