The necessary life function that protects our internal environment from our
external environment is provided by what system?
The integumentary system
The function of movement is provided by what system?
The muscular system
The function of responsiveness is provided by what system?
The nervous system
The function of digestion is provided by what system?
The digestive system
What is anabolism?
When more complex structures are synthesized from simpler ones.
What is catabolism?
When more complex structures are broken down into simpler ones.
Excretion involves what systems?
The respiratory system, the digestive system, and the urinary system.
The reproductive system is controlled by what other system?
The endocrine system.
Which tissue covers the body surface and lines the cavities of the body?
The epithelial tissue.
Name the three steps in cellular respiration.
1) glycolysis
2) citric acid cycle
3) electron transport chain
What is the purpose of ATP?
ATP provides cells with the energy necessary to carry out cellular activities and
functions.
Epithelial cells perform what types of functions?
Secretion and absorption
What are the four basic tissue types?
1) epithelial
2) muscle
3) connective
4) nervous
, Toward or at the body surface is known as what direction?
Superficial
Away from the body surface is what direction?
Deep
Between a more medial and a more lateral structure is what direction?
Intermediate
Toward or at the midline of the body or on the inner side of is what direction?
Medial
Away from the head end or toward the lower part of a structure of the body is
what direction?
Inferior
Toward the head end or upper part of a structure (above) is what direction?
Superior
Toward or at the front of the body is what direction?
Anterior/Ventral
Is the knee proximal or distal to the pelvis?
Distal
Is the elbow proximal or distal to the hand?
Proximal
Toward or at the back of the body is what direction?
Posterior/Dorsal
Closing of a joint is which action?
Flexion
Opening of a joint is which action?
Extension
In anatomical position are the hands in pronation or supination?
Supination
Why are the hands palm forward in anatomical position?
In supination the forearm bones (the radius and ulna) are uncrossed.
Define elevation
upward movement of a structure
Define depression in anatomy
downward movement of a structure
Define retraction
the movement of a structure in the posterior direction
Define protraction
the movement of a structure in the anterior direction
A person standing in anatomical position moves their right wrist laterally toward
the radius - what is this action called?
Radial deviation
This body division includes the head, neck, and trunk.
axial division
This is a vertical plane that divides the body into right and left parts.
sagittal plane
These planes lie vertically and divide the body into anterior and posterior parts.
frontal planes
