NASM CPT Study Guide Deck Flashcards
Nervous System
The body’s communication network
What is this?

Nervous System
Define Central Nervous System
brain and spinal cord; coordinates activity of the body.
What is this?

Central Nervous System
Define Peripheral Nervous System
nerves connecting the CNS to the rest of the body and environment.
What is the nervous system made up of?
Central Nervous System
Peripheral Nervous System
What does this image represent?

The peripheral nervous system
What is the Peripheral Nervous System subdivided into?
Autonomic Nervous System
Somatic Nervous System
What are the functions of the nervous system?
Sensory (changes in the environment)
Integrative (analyze and interpret)
Motor (neuromuscular response)
Define Somatic Nervous System
Part of the peripheral nervous system
Serves outer areas of the body and skeletal muscle
Voluntary control

What is the Autonomic Nervous System?
Involuntary systems (heart, digestion, etc.)
Part of the peripheral nervous system
Divided into Parasympathetic & Sympathetic

What does this image represent?

The autonomic nervous system
What does the Parasympathetic Nervous System do?
Decreases activation during rest and recovery
“rest and digest”

What does the Sympathetic Nervous System do?
Increases activation to prepare for an activity.
“fight or flight”

What is a neuron?
functional unit of the nervous system

What do motor (efferent) neurons do?
Transmit nerve impulses from CNS to effector sites.

What do sensory (afferent) neurons do?
Respond to stimuli; transmit nerve impulses from effector sites to CNS

What do mechanoreceptors do?
sense distortion in body tissues
What do joint receptors do?
respond to pressure, acceleration, and deceleration of joints.

What are golgi tendon organs?
Sense changes in muscle tension.

What are muscle spindles?
Sense changes in muscle length (stretch)

What is a tendon?
connect muscle to bone; provide anchor for muscles to produce force.

What is fascia?
outer layer of connective tissue surrounding a muscle
What are fascicles?
bundle of individual muscle fibers
