The nerves that branch off from the brain and spine compose which part of the nervous system?

The sensory division and motor division are subdivisions of which part of the Nervous System?

The Somatic NS, which is part of the motor division of the Peripheral NS, is responsible for what?

Which of the following is the Autonomic Nervous System NOT responsible for ?

______ Is a nerve cell that responds to stimuli and transmits signals

______ provide support nutrition insulation and signal transmission and outnumber neurons 10 to 1 and area half the mass of the brain

The ___ is the life support and cell body of a neuron.

The ___ is the long extension that generally transmits electrical impulses away from the cell body to other cells

The ___ is “bushy branch looking thing" that is projecting from the soma. They are listeners pick up messages from other cells and convey that info to the rest of the body

The ___ is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. Allows electrical impulses to transmit quickly.

_____ transmit impulses from sensory receptors towards the Central NS (Brain and Spinal Cord)

_____ transmit impulses away from the Central NS and out to your body's muscles and glands

_____ live in the CNS transmit impulses between sensory and motor neurons.

____ is a chemical messenger that carries, boosts, and balances signals between neurons (Nerve Cells), and target cells throughout the body.

True or False: Billions of neurotransmitter molecules work constantly to keep our brains functioning, managing everything from our breathing to our heartbeat to our learning and concentration levels

Naturally occurring chemical that is involved in suppressing autonomic arousal, improves sleep as it creates sleep pressure

Considered to be the energy currency of life, acts as a neurotransmitter in the central and peripheral nervous systems.

It is produced by the hypothalamus and plays a role in social recognition, bonding, and sexual reproduction

inhibit the transmission of pain signals and promote feelings of euphoria. These chemical messengers are produced naturally by the body in response to pain, but they can also be triggered by other activities such as aerobic exercise.7

 For example, experiencing a "runner's high"

A hormone and neurotransmitter, serotonin plays an important role in regulating and modulating mood, sleep, anxiety, sexuality, and appetite. SSRIs are a type of antidepressant medication that balance the levels of this neurotransmitter.

This organic compound acts as a neurotransmitter in the brain and spinal cord.

It plays a role in allergic reactions and is produced as part of the immune system's response to pathogens.

is involved in reward, motivation, and additions. Several types of addictive drugs increase levels of this neurotransmitter in the brain. This chemical messenger also plays an important role in the coordination of body movements.

Also known as adrenaline, it is considered both a hormone and a neurotransmitter. Generally, this is a stress hormone that is released by the adrenal system. However, it functions as a neurotransmitter in the brain. IT is the chemical signature of FEAR.
