Muscular Skeletal System Flashcards
The collective components and structures that work together to move the body: muscular, skeletal, and nervous systems.
Human movement system (HMS)
concept that describes the human body as a chain of interdependent links that work together to perform movement.
Kinetic chain
Nervous system
network of specialized cells called neurons that transmit and coordinate signals, providing a communication network within the human body.
Cellular structure or organelle that contains the majority of the cell’s genetic material in the form of chromosomes.
Nucleus
Tiny cellular structures that perform specific functions within a cell. Examples include nuclei, mitochondria, lysosomes, ribosomes, and the endoplasmic reticulum.
Organelles
The parts of the cell that use nutrients to create energy for the cell; commonly known as the powerhouses of the cell.
Mitochondria
part of the body, such as a muscle or organ, that receives a signal from a neuron to produce a physiological response.
Effector sites
Minerals that have an electrical charge to help transmit nerve impulses throughout the body, such as sodium, potassium, and magnesium.
Electrolytes
A division of the nervous system that includes the brain and spinal cord
Central nervous system (CNS)
Nerves that connect the rest of the body to the central nervous system.
Peripheral nervous system (PNS)
Sensory pathway that relays information to the central nervous system.
Afferent pathway
Efferent pathway
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.
Interneurons
Specialized structures that respond to mechanical forces (touch and pressure) within tissues and then transmit signals through sensory nerves.
Mechanoreceptors
Nerves that serve the outer areas of the body and skeletal muscle and are largely responsible for the voluntary control of movement.
Somatic nervous system
