Flashcards in Skeletal System Vocab Deck (42):
Consists of the bones of the head and trunk of vertebrate.
consists of the bones or cartilage that support the appendages.
the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.
s a network of irregularly-shaped sheets and spikes of bone (trabeculae). The trabeculae are only a few cell layers thick.
hard, dense bones that provide strength, structure, and mobility. The femur (thigh bone) is a long bone.
Short bones are shaped roughly as a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone
bones whose principal function is either extensive protection or the provision of broad surfaces for muscular attachment. These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage.
serve various purposes in the body, such as protection of nervous tissue (such as the vertebrae protect the spinal cord), affording multiple anchor points for skeletal muscle attachment (as with the sacrum), and maintaining pharynx and trachea support, and tongue attachment (such as the hyoid bone).
the shaft or central part of a long bone.
a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.
hyaline cartilage plate in the metaphysis at each end of a long bone
a break or splinter of the bone into more than two fragments.
Occurs when one or more bones in the spine weaken and crumple.
is a break in a cranial bone.
is when the bone breaks into several pieces
is a bone fracture occurring when torque (a rotating force) is applied along the axis of a bone.
a fracture of the bone, occurring typically in children, in which one side of the bone is broken and the other only bent.
a solid swelling of clotted blood within the tissues.
a saucer-shaped membrane bone situated at the back and lower part of the skull
also known as the backbone or spine,
articulate with each other to give strength and flexibility to the spinal column, and the shape at their back and front
lies between adjacent vertebrae in the vertebral column.
the vertebrae immediately below the skull.
compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae
the five vertebrae between the rib cage and the pelvis
a large, triangular bone at the base of the spine
commonly referred to as the tailbone
a thickened ventral plate on each segment of the body of an arthropod.
One of the 12 paired arches of bone that form the skeletal structure of the chest wall (the rib cage).
A break in the bone connecting the breastbone and shoulder
a long bone in the arm or forelimb that runs from the shoulder to the elbow
two large bones of the forearm
the thinner and longer of the two bones in the human forearm, on the side opposite to the thumb.
the carpus is the sole cluster of bones in the wrist between the radius
form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist which forms the connection to the forearm.
the enclosing structure formed by the pelvis, providing attachment for the hind limbs or pelvic fins.
Bone of the leg.
the main bone of the leg,
or calf bone is a leg bone located on the lateral side of the tibia,
