Disorders
Osteoporosis: disorder caused by loss of bone density
Carcinoma: type of skin cancer that originates in skin cells that do not produce pigments
Osteoarthritis: disorder that causes the degeneration of cartilage that covers the surfaces of bone
Tendonitis: inflammation of the tendons caused by excessive stress
Melanoma: type of skin cancer that originates in pigment-producing skin cells
Rheumatoid arthritis: inflammation of freely moveable joints
Acne: skin disorder caused by excess production of sebum
Fill-in-the-Blank
The body maintains a constant temperature because of endothermy which enables homeostasis
The bones of the skull and rib cage make up the axial skeleton
Muscles that cause a joint to bend are called flexors
The ATP used to power muscle contractions is supplied by aerobic processes when oxygen is plentiful. As oxygen becomes depleted, ATP is supplied anaerobic processes
Hair is produced by hair follicles
Cells that are not yet specialized and that can divide indefinitely are called embryonic stem cell
Multiple Choices
The main components of the epidermis are connective tissue and epithelial tissue
Extensor structures cause a join to straighten
A group of similar cells that work together to perform a common function is a tissue
Skull, vertebrae, and the sternum are sets of bones that are part of the axial skeleton
Hair and nails are derived from cells of the epidermis
When a sarcomere is fully contracted myosin and actin completely overlap each other
Periosteum, compact bone, spongy bone, bone marrow are the correct order of structures that compose a bone from the outermost structure to the innermost structure
The structures in the dermis that help regulate body temperature are blood vessels and sweat glands
The functions of the skin include protecting the body from injury, preventing the body from drying out, and protecting the body from infection NOT absorbing nutrients from food
Energy for muscle contraction can be supplied by aerobic processes, anaerobic processes, and glycolysis
Eating a mineral-rich diet and excising regularly can help prevent osteoporosis
Muscle tissue enables the movement of body structures
The heart is NOT part of the immune system
Disorders of the skin include acne, malignant melanomas, and carcinomas NOT osteoporosis
Endothermy is important because it enables organisms to remain active at external temperatures that would slow the activity of ectoderms, sustain strenuous activity for a long period of time, and maintain body temperature in which enzymes will not be inactivated
The condition in which bone density is lost and bones become brittle is called osteoporosis
The wrist is NOT a hinge joint
Each organ belongs to at least one organ system
