What are the bone + joint types?
In the nervous system
Human movement system (HMS)
The collective components and structures that work together to move the body: muscular, skeletal, and nervous systems.
Kinetic Chain
A concept that describes the human body as a chain of interdependent links that work together to perform movement.
Nervous system
A network of specialized cells called neurons that transmit and coordinate signals, providing a communication network within the human body.
Neuron
Specialized cell that is the functional unit of the nervous system. Form the core of the nervous system - includes the brain, spinal cord, + peripheral nerves.
Nervous system (2.0)
Many functions, such as providing sensory information (e.g., pain, sight, taste) to our brain, stimulating human movement through muscle contractions, + keeping the heart + organs functioning.
Nucleus
Cellular structure or organelle that contains the majority of the cell’s genetic material in the form of chromosomes.
Organelles
Tiny cellular structures that perform specific functions within a cell. Examples include nuclei, mitochondria, lysosomes, ribosomes, and the endoplasmic reticulum.
Mitochondria
The parts of the cell that use nutrients to create energy for the cell; commonly known as the powerhouses of the cell.
Effector sites
A part of the body, such as a muscle or organ, that receives a signal from a neuron to produce a physiological response.
Electrolytes
Minerals that have an electrical charge to help transmit nerve impulses throughout the body, such as sodium, potassium, and magnesium.
Central nervous system (CNS)
A division of the nervous system that includes the brain and spinal cord.
Peripheral nervous system (PNS)
Nerves that connect the rest of the body to the central nervous system.
Afferent pathway
Sensory pathway that relays information to the central nervous system.
Efferent pathway
A motor pathway that relays information from the central nervous system to the rest of the body.
