Ch 5 The Nervous, Muscular, and Skeletal Systems Flashcards
Human movement is accomplished through the:
Nervous system, the skeletal system, and the muscular system. These three systems are interdependent and must work together to produce human movement.
Human Movement System (HMS)
The collective components and structures that work together to move the body: muscular, skeletal, and nervous systems.
The fitness professional must have a working knowledge of…
Anatomy and physiology to administer an accurate fitness assessment, program safe exercises, and answer any questions the client may have regarding their fitness program.
Kinetic chain
A concept that describes the human body as a chain of interdependent links that work together to perform movement.
The term kinetic chain refers to…
How muscles, bones and joints, and nerves are linked together (forming a chain) to create movement (kinetic).
Nervous system
A network of specialized cells called neurons that transmit and coordinate signals, providing a communication network within the human body.
The nervous system has many functions, such as:
Providing sensory information (e.g., pain, sight, taste) to our brain, stimulating human movement through muscle contractions, and keeping the heart and organs functioning.
Neurons provide the nervous system with the ability to…
Communicate with itself, as well as with the outside environment.
Neurons process and transmit information through…
electrical and chemical signals.
Neurons form the core of the nervous system, which includes…
The brain, spinal cord, and peripheral nerves.
Neuron
Specialized cell that is the functional unit of the nervous system.
