Physiology

Define this: protective layers of the brain

Meninges

Define this: The innermost membrane which adheres to the surface of the CNS.

Pia mater

Define this: a neuropeptide that functions like a neurotransmitter. It binds to the NK-1 receptor and is involved in pain transmission within the CNS

Substance P

Define this: one of two main divisions of the autonomic nervous system. The sympathetic nervous system's primary process is to stimulate the body's fight-or-flight response.

Sympathetic

Define this: one of the two divisions of the autonomic nervous system. The parasympathetic system is responsible for stimulation of "rest-and-digest" or "feed and breed" activities that occur when the body is at rest, especially after eating, including sexual arousal, salivation, lacrimation (tears), urination, digestion and defecation

Parasympathetic Nervous system

Define this: a monoamine neurotransmitter. Primarily found in the gastrointestinal tract (GI tract), platelets, and the central nervous system (CNS). It is popularly thought to be a contributor to feelings of well-being and happiness.

Serotonin

Define this: one of many neurotransmitters in the autonomic nervous system (ANS). It acts on both the peripheral nervous system (PNS) and central nervous system (CNS) and is the only neurotransmitter used in the motor division of the somatic nervous system.

Acetylcholine

Define this: a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another cell (neural or otherwise)

Synapse

Define this: the most abundant excitatory neurotransmitter in the vertebrate nervous system. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor or the AMPA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, glutamate is involved in cognitive functions like learning and memory in the brain

Glutamate

Define this: the chief inhibitory neurotransmitter in the central nervous system. It plays the principal role in reducing neuronal excitability throughout the nervous system.

GABA

Define this: are endogenous opioid inhibitory neuropeptides. They are produced by the central nervous system and pituitary gland.

Endorphin

Define this: Amino acid that inhibits neurotransmitters in CNS

Glycine

What is serotonin synthesized from>

Trptophan

Define this:
