NASM CPT Ch. 2 Flashcards
What 3 systems make up the Human Movement System?
Muscular, Skeletal, Nervous
The muscular, skeletal and nervous systems responsible for human movement is also referred to as ____________
the kinetic chain
What is the combination and interrelation of the nervous, skeletal and muscular systems?
Human Movement System
What is a conglomeration of cells specifically designed to provide a communication network within the human body?
Nervous System
The ability of the nervous system to sense changes in either the internal or external environment is ____________
Sensory Function
The ability of the nervous system to analyze and interpret sensory info to allow for proper decision making, which produces the appropriate response.
Integrative Function
The neuromuscular response to the sensory information
Motor Function
Cumulative sensory input to the CNS from all mechanoreceptors that sense body position and limb movement
proprioception
The functional unit of the nervous system
neuron
transmits nerve impulses from effector sites (muscles and organs) via receptors to the brain and spinal cord
Sensory (AFFERENT) Neurons
One of the main organ systems and consists of a network of specialized cells called neurons that transmit and coordinate signals, providing a communication network within the body
The Nervous System
What 2 parts make up the nervous system?
Peripheral and Central
System that makes up the brain and spinal cord; primary function is to coordinate the activity of all parts of the body
Central Nervous System
System that contains only nerves and connects the brain and spinal cord to the rest of the body
Peripheral Nervous System
3 functions of the Nervous System
Sensory
Integrative
Motor
Ability of nervous system to sense change in internal/external environment
Sensory Function (ex. muscle stretch - internal; or walking on sidewalk vs sand - external)
ability of the nervous system to analyze and interpret sensory information to allow for proper decision making, which produces appropriate response
Integrative Function
Nervous and Muscular systems response to sensory info
Motor Function (ex. causing a muscle to contract when stretched too far, or changing one’s walking pattern when walking in sand vs sidewalk)
This system is responsible for recruiting muscles, learned patterns or movement and the functioning of every organ
Nervous System
specialized cell that processes and transmits info through both electrical and chemical signs
neuron
this cell forms the core of the nervous system, which includes the brain, spinal cord and peripheral ganglia
neuron
What 3 things make up a neuron?
Dendrite, Cell Body and Axon
What makes up the body (soma) of the neuron?
Nucleus and other organelles, including lysosomes, mitochondria and golgi complex
What is the cylindrical projection from the cell body that transmits nervous impulses to other neurons or effector sites?
The Axon
