Question | Answer |
periosteum: | outermost layer of the bone, made up of fibrous tissue |
compact bone: | dense, hard layers of bone tissue that lie underneath the periosteum |
cancellous (spongy) bone: | contains small spaces like a sponge and is encased in the layers of compact bone |
endosteum: | membranous lining of the hollow cavity of the bone |
diaphysis: | shaft of the long bones |
epiphysis: | ends of the long bone |
bone marrow: | material found in the cavities of bones |
red marrow: | thick, blood-like material found in flat bones and the ends of long bones (location of blood cell formation) |
yellow marrow: | soft, fatty material found in the medullary cavity of long bones |
Long bones: | such as the femur, are every strong and have large surface areas for muscles to attach. |
Short bones: | such as the carpals in the hand, are grouped together to help provide movement. |
Flat bones: | such as the ribs, cover and protect soft body parts. |
Sesamoid bones: | such as the kneecap, are small and rounded; they are found near joints to increase the efficiency of the muscles near that joint. |
Haversian canals: | channels in compact bone that contain blood vessels |
Medullary cavity: | central shaft of long bones that contains yellow bone marrow that is made up of mostly fat cells |
Fossa: | shallow cavity in a bone |
Foramen: | opening in a bone for blood vessels and nerves |
Fissure: | deep, narrow slit in a bone |
Sinus: | hollow cavity in a bone |
Maxilla: | upper jaw bone |
Mandible: | Lower jaw bone |
cervical vertebrae | first set of 7 forming the neck |
thoracic vertebrae | second set of 12 vertebrae |
lumbar vertebrae | third set of 5 larger vertebrae, which forms the inward curve of spine |
joint: | holds bones together and makes movement possible |
articular cartilage: | smooth layer of gristle covering the contacting surface of joints |
meniscus: | crescent-shaped cartilage found in the knee |
intervertebral disk: | cartilagionous pad found between the vertebrae in the spine |
pubic symphysis: | cartilaginous joint at which two public bones fuse together |
synovia: | fluid secreted by the synovial membrane and found in joint cavities |
bursa: | fluid-filled sac that allows for easy movement of one part of a joint over another |
ligament: | flexible, tough band of fibrous connective tissue that attaches one bone to another at a joint |
tendon: | band of fibrous connective tissue that attaches muscle to bone |
aponeurosis: | strong sheet of tissue that acts as a tendon to attach muscles to bone. |
skeletal muscles (striated): | attached to bones by tendons and make body movement possible. |
smooth muscles (unstriated): | located in internal organs such as the walls of blood vessels and the digestive tract. involuntary they respond to impulses from the autonomic nerves |
cardiac muscle: | forms most of the wall of the heart. Its involuntary contraction produces the heartbeat. |
Striated: | made up of voluntary muscles that move all bones, Muscle fibers are arranged in bundles. |
clavicle | collarbone(2) |
scapula | shoulder blade(2) |
sternum: | breastbone |
upper extremities | humerus(2) phalanges (28) ulna (2) metacarpals (10) radius (2) carpals (16)) |
pelvic bones | (3 pairs fused together) illium (2) ischium (2) pubis (2) |
lower extremities: | femur (2) tarsals(4) patella (2) metatarsals(10) tibia(2) phalanges(28) fibula(2) |
