Term
Nervous System
Definition
The communication network within the body
Term
Sensory Function
Definition
The ability of the nervous system to sense changes in either the internal or external environment
Term
Integrative Functions
Definition
The ability of the nervous system to analyze and interpret sensory information to allow for proper decision making which produces the appropriate response
Term
Motor Function
Definition
The neuromuscular response to the sensory information
Term
Neuron
Definition
The functional unit of the nervous system
Term
Sensory (afferent) Neurons
Definition
Transmit nerve impulses from effector sites to the brain or spinal cord
Term
Interneurons
Definition
Transmit nerve impulses from one neuron to another
Term
Motor (efferent) Neurons
Definition
Transmit nerve impulses from the brain and spinal cord to efferent sites
Term
Central Nervous System
Definition
Composed of the brain and spinal cord
Term
Peripheral Nervous System
Definition
Cranial and spinal nerves that spread throughout the body
Term
Mechanoreceptors
Definition
Sensory receptors responsible for sensing distortion in body tissues
Term
Muscle Spindles
Definition
Receptors sensitive to change in length of the muscle and rate of that change
Term
Golgi Tendon Organs
Definition
Receptors sensitive to change in tension of the muscle and the rate of that change
Term
Joint Receptors
Definition
Receptors that respond to pressure, acceleration, and deceleration of the joint
Term
Axial Skeleton
Definition
Portion of the skeletal system that consists of the skull, rib cage, and vertebral column
Term
Appendicular Skeleton
Definition
Portion of the skeletal system that includes the upper and lower extremities
Term
Depression
Definition
Flattened or indented portion of bone, which can be a muscle attachment sign
Term
Process
Definition
Projection protruding from the bone where muscles, tendons, and ligaments can attach
Term
Arthrokinematics
Definition
Joint motion
Term
Synovial Joints
Definition
Joints that are held together by a joint capsule and ligaments and are most associated with movement in the body
Term
Nonsynovial Joints
Definition
Joints that do not have a joint cavity, connective tissue, or cartilage
Term
Ligament
Definition
Primary connective tissue that connects bones together and provides stability, input to the nervous system, guidance, and limitation of improper joint movement
Term
Sarcomere
Definition
The functional unit of muscle that produces muscular contraction and consists of repeating sections of actin and myosin
Term
Neural Activation
Definition
The contraction of a muscle generated by a neural stimulation
Term
Motor Unit
Definition
A motor neuron and all of the muscle fibers it innervates
Term
Neurotransmitter
Definition
Chemical messengers that cross synapses to transmit electrical impulses from the nerve to the muscle
