|
Kinetic chain
|
The combination and interrelation of the nervous, muscular, and skeletal systems. Makes up the human mvmt. system.
|
|
Nervous system
|
The communication network within the body. A conglomeration of billions of neurons forming nerves. Central command center.
|
|
The 3 primary functions of the nervous system
|
Sensory, integrative, and motor functions.
|
|
Sensory function
|
The ability of the nervous system to sense changes in either the internal or external environment.
|
|
Integrative function
|
The ability of the nervous system to analyze and interpret sensory information to allow for proper decision making, prod. approp. response.
|
|
Motor function
|
The neuromuscular response to the sensory information.
|
|
What dictates all movement?
|
The nervous system.
|
|
Neuron
|
The functional unit of the nervous system.
|
|
3 main parts of a neuron
|
The cell body(soma), axon, and dendrites.
|
|
What is the cell body of a neuron?
|
Contains a nucleus and other organelles such as lysosomes, mitochondria, and a Golgi complex.
|
|
What is the axon of a neuron?
|
A cylindrical projection from the cell body that transmits nervous impulses to other neurons or effector sites(muscles, organs, neurons).
|
|
What are the dendrites of a neuron?
|
Responsible for gathering info. from other structures back into the neuron.
|
|
What are the 3 main functional classifications of neurons? Type depends on direction of nerve impulses
|
Sensory(afferent) neurons, interneurons, and motor(efferent) neurons.
|
|
Sensory(afferent) neurons
|
Transmit nerve impulses from effector sites to the brain or spinal cord.
|
|
Interneurons
|
Transmit nerve impulses from one neuron to another.
