What is meant by “systems integration” and why it is important
the process of bringing together the component sub-systems into one system. Its important because it is all the systems that make up the body.
What is the nervous systems primary function+component
control system of the body, primary component is neuron, responds to acute challenges of the body
What 2 parts make of the nervous system?
Centeral + Peripheral
What is the Centeral (nervous system) made up of?
Brain + Spinal Chord
What is the Peripheral (nervous system) made up of?
Motor+Autonomic
Afferent Neurons
nerves that carry electric impulses toward the brain and spinal cord (sensory neurons)
Efferent neurons
nerves that carry electric impulses away from the brain and spinal cord (motor neurons)
Somatic
part of the nervous system that controls voluntary action
Autonomic
part of the nervous system that regulates involuntary action
Sympathetic
part of the autonomic nervous system that tends to act in opposition to the parasympathetic nervous system, especially under conditions of stress (“fight or flight”)
Parasympathetic
part of the autonomic nervous system that tends to act in opposition to the sympathetic nervous system (“rest and digest”)
Stroke Volume
the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction.
Cardiac Output
the quantity of blood pumped by the heart in a given period of time, typically measured in liters per minute.
What is the Muscular system primary function+component
Provide movement, primary component is muscle fiber
Types of muscle in Muscular system
