cells
the basic unit of all living things from bacterial to plants and animals and including human beings; a minute mass of protoplasm capable of performing all the fundamental functions of life
cells
a collection of similar cells that perform a specialized function
tissue
the physical foundation of the body, comprising 206 bones that vary in size and shape that are connected by movable and immovable joints
skeletal system
the uppermost and largest bone in the arm, extending from the elbow to the shoulder
humerus
a heavy, long bone that forms the leg above the knee
femur
a colorless, jelly-like substance found inside cells, in which food elements such as protein, fats, carbohydrates, mineral salts, and water are present
protoplasm
fibrous tissue that binds together, protects, and supports the various parts othe body. Examples include bone, cartilage, ligaments, tendons, fascia, and fat (adipose tissue)
connective tissue
the study of anatomy, structure, and function of the bones
osteology
the inner and larger bone of the forearm (lower arm); it is attached to the wrist and located on the side of the little finger
ulna
the larger of the two bones that form the leg below the knee. The tibia may be visualized as a bump on the big-toe side of the ankle
tibia
the dense, active protoplasm found in the center of the cell that plays an important part in cell reproduction and metabolism
nucleus
the technical term for fat; it gives smoothness and contour to the body
adipose tissue
a joint disease
osteoarthritis
the smaller bone in the forearm (lower arm) on the same side as the thumb
radius
the smaller of the two bones that form the leg below the knee. The fibula may be visualized as a bump on the little-toe side of the ankle
fibula
a fluid found within the nucleus of the cell that contains proteins and DNA
nucleoplasm
tissue that contracts and moves various parts of the body
muscle tissue
a connection between two or more bones of the skeleton
joint
the wrist; a flexible joint composed of a group of eight small, irregular bones held together by ligaments
carpus
also known as the accessory bone; forms the kneecap joint
patella
an acid that determines our genetic makeup
deoxyribonucleic acid (DNA)
a protective covering on body surfaces, such as the skin, mucous membranes, the tissue inside the mouth, the lining of the heart, digestive and respiratory organs, and glands
epithelial tissue
how many bones are in the adult human body
206
bones of the palm of the hand; parts of the hand containing five bones between the carpus and phalanges
metacarpus
also known as the ankle bone of the foot; one of three bones (along with the tibia and fibula) that make up the ankle joint
talus
the part of the protoplasm that exists outside of the nucleus and inside the cell wall; the protoplasm surrounds the nucleus and is needed for growth, reproduction, and self-repair
cytoplasm
tissue that carries messages to and from the brain and controls and coordinates all body functions
nerve tissue
how many bones are humans born with
300
also known as digit; bone of the fingers or toes
phalanges
one of three subdivisions of the foot comprising seven bones (talus, calcaneous, navicular, three cuneiform bones, and the cuboid). The other two subdivisions are the metatarsal and the phalanges. All three subdivisions comprise 26 bones
tarsal
a chemical energy used within cells for metabolism
adenosine triphosphate (ATP)
in plants and animals, a structure composed of specialized tissues that allow it to perform specific functions
organ
more than half the bones in the adult human body are found here
Hands and feet
painful inflammation involving the carpus area
carpal tunnel syndrome
one of three subdivisions of the foot comprising five bones—which are long and slender, like the metacarpal bones of the hand—that help make up the foot. The other two subdivisions are the tarsal and phalanges. All three subdivisions comprise 26 bones
metatarsal
