Chapter 2 - The Nervous System & Endocrine System

The [blank_start]nervous system[blank_end] includes the brain and the spinal cord

Spinal reflexes are simple, automatic behaviors that are processed in the spinal cord

The [blank_start]peripheral[blank_end] nervous system comprises all the nerves outside the central nervous system

The two subdivisions of the peripheral nervous system are?

The [blank_start]somatic[blank_end] nervous system communicates sensory information received by sensory receptors along sensory nerves to the central nervous system and carries messages from the central nervous system along motor nerves to perform voluntary muscle movements.

The [blank_start]autonomic[blank_end] nervous system regulates involuntary functions such as heartbeat, blood pressure, breathing, and digestion

The autonomic nervous system has two subdivisions : the sympathetic nervous system & the parasympathetic nervous system

The [blank_start]sympathetic[blank_end] nervous system produces rapid physiological arousal in response to perceived threats or emergencies. These bodily changes collectively represent the fight-or-flight response—they physically prepare you to fight or flee from a perceived danger.

The [blank_start]parasympathetic[blank_end] nervous system conserves and maintains the body’s physical resources.

The [blank_start]endocrine[blank_end] system is made up of glands located throughout the body that secrete hormones into the bloodstream

[blank_start]Hormones[blank_end] are chemical messengers secreted into the bloodstream primarily by endocrine glands

The [blank_start]hypothalamus[blank_end] serves as the main link between the nervous system and endocrine system

The [blank_start]pituitary gland[blank_end], a pea-sized gland just under the brain, controls hormone production in other endocrine glands.

A set of glands called the [blank_start]adrenal glands[blank_end] is involved in human stress response
