Connects bone to bone | Ligament |
the outer layer of the skin | epidermis |
the lower layer of skin | dermis |
the brown pigment that determines human skin color | melanin |
the tough, white tissue that covers bones | periosteum |
a type of connective tissue that is softer and more flexible than bone | cartilage |
a tough, flexible band of connective tissue that holds bones together at a joint | ligament |
the microscopic unit of compact bone | osteon |
where two bones are fused together | immovable joint |
four functions of skeletal system | support and movement, protection, mineral storage, blood cell production |
when bones act like a rigid bar turning on a fulcrum act as a __________. | lever |
the predominant type of lever in the body | 3rd class lever |
type of lever with the fulcrum in the middle | 1st class lever |
type of lever with the load in the middle | 2nd class lever |
what is contained in the central cavity of a bone | marrow |
what is formed from additional cells/layers as a result of friction to protect the deeper layers of the skin? | callus |
type of gland for cooling and excretion of wastes | sweat |
the layer below the skin which is not really part of the skin | subcutaneous layer |
the type of tissue the epidermis is made of | epithelial tissue |
type of gland next to each hair follicle | oil gland |
functions of the subcutaneous layer | support, cushioning, insulation |
the study of the organs and structures of the body | anatomy |
the study of how organs and structures function | physiology |
**similar to mammals in body systems, characteristics, and physical needs | |
**different from mammals, being created in the image of God--having immortal souls, and the ability to distinguish right/wrong | human |
cells-->tissues-->organs-->systems | |
Cells work together to make up tissues | tissues work together to make organs |
tissue that supports, connects, and protects other body structures | connective tissue |
a small opening in the epidermis that releases oil onto the skin surface | pore |
very hard bone made of circular layers | compact bone |
the material at the center of some bones that produces blood cells | bone marrow |
a band of connective tissue that attaches muscle to bone | tendon |
another name for a voluntary muscle | skeletal muscle |
a muscle that has a pattern of dark and light bands, called striations, found in both skeletal and cardiac muscles | striated muscle |
a muscle that is not controlled at will | involuntary muscle |
a striated, involuntary muscle found in the heart | cardiac muscle |
tissue that receives and transmits electrochemical impulses to coordinate the functions of the body | nerve tissue |
tissue that contracts either to move the body or to move substances through the body | muscle tissue |
hard and rigid bone with empty spaces throughout | spongy bone |
the connection between two or more bones | joint |
the organ system that an animal or human uses to move around | muscular system |
an involuntary muscle without striations found in internal organs | smooth muscle |
the study of the organs and structures of the body | Anatomy |
the study of how organs and structures function | Physiology |
a body tissue that carries messages back and forth between the brain and every other part of the body | nerve tissue |
A body tissue that contracts or shortens, making body parts move. | muscle tissue |
A body tissue that covers the surfaces of the body, inside and out | epithelial tissue |
a small tubular cavity containing the root of a hair | hair follicle |
the organ system that an animal or human uses to move around | Muscular System |
a muscle that is controlled at will | voluntary muscle |
Connects muscle to bone | Tendon |
A muscle that is attached to the bones of the skeleton and provides the force that moves the bones. | skeletal muscle |
Type of lever that is the skull on the top vertebra | 1st class |
Type of lever that is predominant in the skeleton and the elbow is an example | 3rd class |
Type of lever that is the foot with the calf muscle as the effort | 2nd class |
