|
Kinetic Chain
|
The combination and interrelation of the nervous, muscular and skeletal systems
|
|
Nervous System
|
The communication network withing the body
|
|
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 info to allow for proper decision making, which produces the appropriate response
|
|
Motor Function
|
The neuromuscular response to the sensory information
|
|
Neuron
|
The functional unit of the nervous system
|
|
Sensory (afferent) Neurons
|
Transmit nerve impulses from effector sites to the brain or spinal cord
|
|
Interneurons
|
Transmit nerve impulses from one neuron to another
|
|
Motor (efferent) Neurons
|
Transmit nerve impulses from the brain & spinal cord to effector sites
|
|
Central Nervous System
|
Composed of the brain and spinal cord
|
|
Peripheral Nervous system
|
Cranial & spinal nerves that spread throughout the body
|
|
Mechanoreceptors
|
Sensory receptors responsible for sensing distortion in body tissues
|
|
Muscle spindles
|
Receptors sensitive to change in length of the muscle and the rate of that change
|
|
Golgi Tendon Organs
|
Receptors sensitive to change in tension of the muscle and the rate of that change
|
|
Joint Receptors
|
Receptors that respond to pressure, acceleration, and deceleration in the joint
|
|
Skeletal System
|
The body's framework, composed of bones and joints
|
|
Bones
|
Provide the resting ground for muscles and protection of vital organs
|
|
Joints
|
The movable junction where two or more bones meet
|
|
Axial Skeleton
|
Portion of the skeletal system that consists of the skull, rib cage, and vertebral column
|
|
Appendicular Skeleton
|
Portion of the skeletal system that includes the upper and lower extremities
|
|
Depression
|
Flattened or indented portion of bone, which can be a muscle attachment site
|
|
Process
|
Projection protruding from the bone where muscles, tendons, and ligaments can attach
|
|
Arthrokinematics
|
Joint motion
|
|
Synovial Joints
|
Joints that are held together by a joint capsule and ligaments and are most associated with movement in the body
|
|
Nonsynovial Joints
|
Joints that do not have a joint cavity, connective tissue, or cartilage
|
|
Ligament
|
Primary connective tissue that connects bones together and provides stability, input to the nervous system, guidance, and the limitation of improper joint movement
|
|
Muscular system
|
Series of muscles that moves the skeleton
|
|
Tendons
|
Connective tissues that attach muscle to bone and provide an anchor for muscles to produce force
|
|
Sarcomere
|
The functional unit of muscle that produces muscular contraction and consists of repeating sections of actin and myosin
|
|
Neural Activation
|
The contraction of muscle generated by neural stimulation
|
|
Motor Unit
|
A motor neuron and all of the muscle fibers it innervates
|
|
Neurotransmitter
|
Chemical messenger that cross synapses to transmit electrical impulses from the nerve to muscle
|
