SUPPORT AND MOVEMENT

Endocrine glands

are responsible for secreting a variety of information carriers known as hormones into the bloodstream in order to trigger action in other tissues of the body.

Inputs

are required for information processing, followed by evaluation and decision- making, and then outputs are generated.

Data handling

requires contributions from both the neurons and the hormones.

Sense organs

, also known as spindle organs, are the terminal points of nerves found within muscles.

musculoskeletal system

The __ of the body is always in motion. 

contractions

Multiple muscle _ are usually responsible for producing a movement.

continuous

A _ cycle of brief exchanges of give-and-take characterizes the action of the body.

Muscles

_ function together in pairs.

information

The _ that the brain receives about the posture and location of the body and limbs comes from the sensory systems that are built into the muscles

proprioceptive sense

enables us to "know" that our fingers are clenched or that our knee is bent even though we do not need to look or feel for this information. 

conscious awareness

A __ of the discomfort prompts the body to take evasive or defensive action.

Sense organs

also known as spindle organs, are the terminal points of nerves found within muscles.

senses

The _ are the entry points for information into the body.

Tiny electrical

impulses can be thought of as the "language" of the nervous system.

unconscious part

of the brain then performs an automatic analysis of the data and sends impulses to various parts of the body in order to maintain an internal environment that is optimal for the body's functioning.

selective awareness

As part of the mind's __, we have the ability to choose whether or not to pay attention to certain things.

smell

The brain receives multiple streams of nerve signals referred to as "_" from the nose.

nerves

perform their functions very quickly, usually within a few hundredths of a second.

 microreceptors

are responsible for monitoring conditions inside the body and sending data about those conditions to the unconscious part of the brain.
