Questions and Answers
What are the six levels of organization in the body? - ANS-atom, molecule,
macromolecule, organelle, cell, tissue, organ, system of organs, and organism
The necessary life function that protects our internal environment from our external
environment is provided by what system? - ANS-Integumentary system
The function of movement is provided by what system? - ANS-Muscular system
The function of responsiveness is provided by what system? - ANS-Nervous system
The function of digestion is provided by what system? - ANS-Digestive system
What is anabolism? - ANS-The building of muscle from obtained proteins and nutrients
What is catabolism? - ANS-The process of breaking down molecules to form simpler
ones for energy
Excretion involves what system? - ANS-Urinary system
Why are the hands supine in the anatomical position? - ANS-Because there are two
bones in the forearm, the radius and ulna which cross over one another but when they
are supine, the bones are independent of one another
Define elevation - ANS-The upward movement of a structure
Define depression - ANS-The downward movement of a structure
Define retraction - ANS-moving a body part backward and parallel to the ground
Define protraction - ANS-moving a body part forward and parallel to the ground
This body division includes the head, neck, and trunk - ANS-Axial division
This is a vertical plane that divides the body into right and left parts - ANS-Sagittal plane
These planes lie vertically and divide the body into anterior and posterior parts - ANS-
Coronal plane and Horizontal plane
, A transverse plane divides the body into these two parts - ANS-Superior and inferior
portions
These cuts/sections are made diagonally between the horizontal and vertical planes -
ANS-Diagonal cuts
This body cavity protects the nervous system - ANS-Dorsal body cavity
This body cavity encases the brain - ANS-Cranial cavity
This cavity encloses the spinal cord - ANS-Spinal cavity
The frontal plane is also known as the what plane? - ANS-Coronal plane
The ventral body cavity is divided into these two cavities - ANS-Thoracic cavity and the
abdominopelvic cavity
This cavity encloses the heart - ANS-Pericardial Cavity
The outer surfaces of the organs and body cavities are covered by this double layered
membrane called the - ANS-Serous membrane
What is pleurisy - ANS-The inflammation of tissues that line the lungs and chest cavity
The abdominopelvic region is divided into what four quadrants? - ANS-LUQ, LLQ, RUQ,
RLQ
This region surrounds the naval - ANS-Umbilical region
This region houses the pelvis - ANS-the Pelvic Cavity
This cavity houses the teeth and tongue - ANS-The buccal cavity
This cavity houses the eyes - ANS-Orbital cavity
Joints are lined with what? - ANS-Synovial tissue
This cavity contains the tiny ear bones, name them. - ANS-The tympanic cavity;
ossicles, the malleus, incus, and the stapes
Explain why active metabolizing cells need to be relatively small - ANS-The cell must be
able to obtain nutrients and excrete waste at a speed fast enough to fulfill the cells
needs. As the cell gets larger, the surface area decreases which leads the metabolism
to be relatively limited
