(2.1) The Biology Behind Our Behavior

Which are parts of a neuron?

- axon - dendrites - myelin sheath

The endocrine is one large gland.

False

Autonomic

The part of the peripheral nervous system that controls how your organs work

Transmission

The process of sending a message

How does the electrochemical process help you?

- it carries messages through neurons - it allows you to move your muscles

Identify the major functions of the endocrine system.

- metabolism - puberty - body temperature

Neuron

A special cell that has a cell body, axon, and dendrites

Which are two major divisions of the peripheral nervous system?

Autonomic and somatic nervous systems

Pavlov's dogs salivated at the sight of a juicy steak. The salivation was an involuntary response. Which nervous system is involved?

Autonomic nervous system

Which structure in your body is responsible for nerual communication?

Brain

Dendrites

Branching part of the neuron that receives transmissions from other neurons

Tina is a ballerina. Which part of the brain is responsible for her graceful movements, posture, and balance?

Cerebellum

Terminal Branches

Connect to muscles to relay information for how they should move

Cell Body

Contains the nucleus of the cell

Emilio has a charismatic personality and great control over his emotions. When there's a crisis, Emilio is always calm and planning what to do next. Which part of the brain is responsible for the traits described?

Frontal lobe

Myelin Sheath

Insulation that speeds up transmissions from other neurons

Axon

One long fiber with branches at the end

Paula has a hard time reading the tiny print in her book. She squeezes her eyes into a squint and it helps. Paula had control of squinting, so what nervous system is involved?

Somatic nervous system

Somatic

The part of the peripheral nervous system responsible for your voluntary body movements

How do sodium and potassium ions transfer in and out of an axon?

Through "gates" that open up

Autonomic and somatic nervous systems are different based on voluntary and involuntary control of body movements and organ functions.
