Pesonal Fittnes Training - Nervous, muscular, & Skeletal System

Cellular structure or organelle that contains the majority of the cells genetic material in the form of chromosomes.

Tiny cellular structures that perform specific functions within the cell. Examples include lysosomes, nuclei, mitochondria, ribosomes, and endoplasmic reticulum.

The part of the cell that use nutrients to create energy for the cell; commonly known as the powerhouse of the cell.

A part of the body such as a muscle or organ, that receives a signal from a neuron to produce a physiological response.

Minerals that have an electric charge to help transmit nerve impulses throughout the body.

A division of the nervous system that includes the brain and spinal cord.

Nerves that connect the rest of the body to the central nervous system

Sensory pathway that relates information to the central nervous system

A motor pathway that relays information from the central nervous system to the rest of the body

Neurons located within the spinal cord and brain that transmit impulses between afferent and efferent neurons.

Specialized structures that respond to mechanical force, such as touch and pressure within tissues and then transmit signals throughout sensory nerves.

Nerves that serve the outer areas of the body and skeletal muscle and largely responsible for the voluntary control of movement.

A division of the peripheral nervous system that supplies neural input to organs that run the involuntary process of the body.

Example: circulating, blood, digesting food and producing hormone.

Subdivision of the autonomic nervous system that works to increase neural activity and put the body in a heightened state.

Subdivision of the autonomic nervous system that works to decrease neural activity and put the body in a more relaxed state.

Ability of the nervous system to sense changes in either the internal or external environment.

The bodies ability to naturally sense its general orientation and relative position of its parts.

The ability of the nervous system to analyze and interpret the sensory information to allow for proper decision-making, which produces an appropriate response.

The neuromuscular or (nervous and muscular systems) response to the integrated sensory information.

Sensory receptors sensitive to change in length of the muscle and the rate of the change.

Neurological signal from the muscle spindle that causes a muscle to contract to prevent excessive lengthening.

A specialized sensory receptor located at the point where skeletal muscle fibers insert into the tendons of skeletal muscle; sensitive to change in muscular tension and rate of tension change.

Receptors located in and around the joint capsule that respond to pressure, acceleration, and deceleration of the joint

The concept that the brain will continually change or grow reforming neural pathways throughout an individuals entire lifespan.

The interconnection of neurons in the brain and spinal cord.

Specific movements throughout the coordinated effort of the sensory and motor subsystems.

A description of the bones of the body

A condition of reduced bone mineral density, which increases risk of bone fracture.

The sites were two bones meat and movement occurs as a result of muscle contraction.

A division of the skeletal system, consisting of the skull, the rib cage and the vertebral column.

A division of the skeletal system, consisting of the arms, legs and pelvic girdle

• Stage one cognitive the client is just learning the skill.
• Stage two associative client begins to understand the skill
• Stage three autonomous the client has mastered the skill.
