The elbow is proximal to the shoulder
False
Physiology is the study of the structure of body parts and their relationships to one another
False
A tissue consists of groupes of similar cells that have a common function
True
The term appendicular describes the limbs and their attachments to the body
True
Desmosomes are small extensions that increase the surface area of an exposed cell
False
In osmosis, movement of water occurs toward the solution with the lower solute concentration
False
Solutions that have a greater solute concentration than the cytoplasm are called hypotonic
False
Diffusion always requires a carrier protein
False
The golgi apparatus is the largest internal cell structure and is visible with the light microscopes used in normal labs
False
Microfilaments are thin strands of the contractile protein myosin
True
The cell (plasma) membrane normally contains cholesterol
True
All organelles are bounded by a membrane
False
The brain is found within the ventral cavity of the human body
False
Microtubules are hollow tubes made of subunits of the protein tubulin
True
Exocytosis is a form of active transport
True
The shock-absorbing pads between the vertebrae are formed from fibrocartilage
True
Epithelial tissues always exhibit polarity; that is, they have a free (apical) surface and a basal surface
True
Simple cuboidal epithelia are usually associated with secretions and absorbtion
True
Merocrine glands produce their secretions by accumulating their secretions internally and then repturing the cell
False
The basic difference between dense irregular and dense regular connective tissues is in the amount of elastic fibers and adipose cells present
False
The protein found in large amounts in the outermost layer of epidermal cells is collagen
False
A blister from a burn is best described as a third-degree burn
False
The most dangerous skin cancer is cancer of the melanocytes
True
The hypodermis is composed of adipose and dense connective tissue
False
The dermis is highly vascularized
True
There are four pigments that contribute to skin color: melanin, carotene, chlorophyll, and hemoglobin
False
Hematopoiesis refers to the formation of blood cells within the red marrow cavities of certain bones
True
The structural unity of compact bone (osteon) resenbles the growth rings of a tree trunk
True
Bones are classified by whether they are weight-bearing or protective in function
False
An osteon contains osteocytes, lamellae, and a central canal, and is found in compact bone only
True
The amount of movement permitted by a particular joint is the basis for the functional classification of joints
True
Hinge joints permit movement in only two planes
False
Synovial fluid is a viscous material that is derived by filtration from blood.
True
The major role of ligaments at synovial joints is to help direct movement of the joint and prevent undersirable movement
True
Movement at the hip joint does not have as wide a range of motion as at the shoulder joint
True
A person who has been diagnosed with a sprained ankle has an injury to the ligaments that attach to that joint
True
a movement of the forearm in which the palm of the hand is turned from posterior to anterior is supination
True
Moving the arm in a full circle is an example of circumduction
True
The structural classification of joints is based on the composition of the binding material and the presence or absence of a joint cavity
True
A person who has been diagnosed with rheumatoid arthritis would be suffering loss of the synovial fluids
False
Bending the tip of the finger exhibits flexion
True
A nerve cell and all the muscle cells lthat it stimulates are referred to as a motor end plate
False
One of the functions of skeletal muscle contraction is production of heat
True
The effect of the neurotransmitter (Ach) on the muscle cell membrane is to modify its permeability properties temporarily
True
