What are the basic life processes?
Organization, metabolism, responsiveness, movement, and reproduction
In humans, additional requirements include growth, differentiation, respiration, digestion, and excretion.
Define metabolism.
The ability to use energy to perform vital functions, such as growth, movement, and reproduction.
What does responsiveness refer to in physiology?
The body’s ability to detect and respond to changes.
What is meant by movement in the context of basic life processes?
Includes motion of the whole body, individual organs, single cells, and even tiny structures inside cells.
What is growth?
An increase in body size resulting from an increase in the size of existing cells, an increase in the number of cells, or both.
What is differentiation?
The development of a cell from an unspecialized to a specialized state.
What does reproduction refer to in physiological terms?
Formation of new cells for tissue growth, repair, or replacement, or the production of a new individual.
Define homeostasis.
The existence and maintenance of a relatively constant environment within the body despite fluctuations in either the external or internal environment.
What is the anatomical position?
The standard reference position of the body used to describe the location of structures.
What does the coronal/frontal plane do?
Divides the body into anterior and posterior parts and is oriented vertically.
What is the mid-sagittal plane?
A plane that passes through the center of the body, dividing it into equal right and left halves.
What does the transverse/axial plane divide?
Divides the body into superior and inferior parts.
What is flexion?
Decreases the angle of a joint.
What is extension?
Increases the angle of a joint.
Define hyperextension.
Extending a joint beyond the straight or neutral position.
What is dorsiflexion of the foot?
Decreasing the angle between the dorsum of the foot and the lower leg, moving foot and toes upward.
What is plantar flexion of the foot?
Extending the ankle joint, moving foot and toes downward.
Define eversion.
An outward stress movement of the foot at the ankle joint.
What is inversion?
An inward stress movement of the foot applied without rotation of the leg.
What is abduction?
Lateral movement of the arm or leg away from the body.
What is adduction?
Movement of the arm or leg toward the body.
Define supination.
A rotational movement of the hand into the anatomical position (palm up).
What is pronation?
A rotation of the hand into the opposite of the anatomical position (palm down).
What does protraction mean?
A movement forward from a normal position.
