Protection, temperature regulation, sensation
integumentary
Support, protection, movement, mineral/fat storage, blood
skeletal
Movement, posture, heat production
muscular
Control/regulation/coordination of other systems, sensation, memory
nervous
Control/regulation of other systems
endocrine
Exchange and transport of materials
cardiovascular
Immunity, fluid balance
lymphatic
Gas exchange, acid-base balance
respiratory
Breakdown and absorption of nutrients, elimination of waste
digestive
Excretion of waste, fluid and electrolyte balance, acid-base balance
urinary
Continuity of genetic information (reproduction)
male reproductive
Reproduction, nurturing of offspring
female reproductive
• Existence and maintenance of a relatively constant environment within the body
HOMEOSTASIS
• Homeostatic mechanisms such as _____ and ______ normally maintain body temperature near an ideal normal value, or set point.
sweating and shivering
• Mechanism that maintains homeostasis
NEGATIVE FEEDBACK MECHANISM
component of negative feedback mechanism that is part of the brain establishes the set point around which the variable is maintained
Control center
component of negative feedback mechanism that monitors the value of a variable, such as body temperature
Receptor
component of negative feedback mechanism that can change the value of the variable such as the sweat glands
Effector
Deviation from set point becomes even greater.
This stimulates additional contractions, which result in additional stretching.
POSITIVE FEEDBACK MECHANISM
- The subject stands erect with the face directed forward
- The upper extremities are placed at the sides.
- The palms of the hands are turned forward
Anatomical Position
• The subject is lying face upward
Supine
• The subject is lying face downward
Prone
Toward the head end or upper part of a structure or the body
Superior
above, up
Away from the head end or toward the lower part of a structure or the body
Inferior
below, down
Towards or at the front of the body, ventral mean belly
Anterior (front, ventral)
Towards the back of the body; behind
Posterior (back, dorsal)
