A connective tissue partition that subdivides an organ


One of three bones who fusion creates the coxa

External Acoustic Canal

Passageway in the temporal bone that leads to the tympanum


Distal portion of the arm between the elbow and wrist

Cribriform Plate

Portion of the ethmoid bone of the skull that contains the foramnia used by the axons of the olfactory receptors en route to olfactory bulbs of the cerebrum


A class of steroid sex hormones that includes estradiol


A fibrocartilage pad between opposing surfaces in a joint


the wrist


movement in a superior, or upward direction


A collagenous band that connects skeletal muscle to an element of the skeleton


a turning outward


layer that surrounds a bone, consisting of an outer fibrous and inner cellular region

Auditory ossicles

The bones of the inner ear: malleus, incus, and stapes


terminal portion of the spinal column, consisting of relatively tiny, fused vertebrae


A small, elevated articular process; used to refer to the rounded distal surface of the humerous that articulates


a cell that dissolves the fibers and matrix of bone

Spinous Process

Prominent posterior projection of a vertebra, formed by the fusion of two laminae


A fibrous aphiarthrosis, such as that between adjacent vertebrae or between the pubic bones of the coxae


inflammation of a joint


A small localized elevation on a bony surface

Endochondral Ossification

The conversion of a cartilaginous model to bone; the characteristic mode of formation for skeletal elements other than the bones of the cranium, the clavicles, and sesamoid bones


The largest of the three bones whose fusion creates a coxa

Os Coxae/ossa coxae

a bone of the hip; formed by the fusion of the ilium, ischium, and pubis


a break or crack in the bone

Pubic Symphysis

Fibrocartilaginous amphiarthrosis between the pubic bones of the ossa coxae


Elevation of the superior surface of the foot


a bone cell responsible for the maintenance and turnover of the mineral content of the surrounding bone


an articulation that permits a small amount of movement


movement away from the midline


the heelbone, largest of the tarsal bones


shallow depression or furrow in the surface of a bone

Glenoid fossa

rounded depression that forms the articular surface of the scalpula at the shoulder joint

Calcaneal tendon

large tendon the inserts on the calcaneus; tension on this tendon produces plantar flexion of the foot; also called the Achilles tendon

Coracoid Process

a hook-shaped process of the scalpula that projects above the anterior surface of the capsule of the shoulder joint


thick bony struts that connect the vertebral body with the articular and spinous processes


inferior surface of the foot


hormone secreted by C cells of the thyroid when calcium ion concentrations are abnormally high; restores homeostasis by increasing rate of bone deposition and renal rate of calcium loss at the kidneys


tissue that fills internal cavities in bones; may be dominated by hemopoietic cells (red marrow) or adipose tissue (yellow marrow)


the anterior, inferior component of the os coxae


inferior (downward) movement of a body part


head of a long bone


one of the five bones of the foot that articulate with the tarsals (proximally) and the phalanges (distally)

Hard palate

the bony roof of the oral cavity, formed by maxillary and palantine bones


a turning inward


a large, roughened elevation on a bony surface


a rounded articular projection on the surface of the bone


a relatively soft, felxible, fibrous region between two flat bones in the developing skull


movement that reduces the angle between two articulating bones; the opposite of extension


small sac filled with synovial fluid that cushions adjacent structures and reduces friction


rotation of the forearm such that the palm faces anteriorly

Cancellous bone

spongy bone, composed of a network of bony struts


bone of the finger or toes

White blood cells

Leukocytes; the granulocytes and agranulocytes of the blood


the thoracic and abdominopelvic regions


basic histological unit of compact bone, consisting of osteocytes organized around a central canal and seperated by concentric lamellae

Appositional growth

enlargement of a bone by the addition of cartilarge or bony matrix at its surface


a movement at a synovial joint where the distal end of the bone describes a circle but the shaft does not rotate


ability to contract, possesed by skeletal, smooth, and cardiac muscle cells

Joint capsule

dense collagen fiber fiber sleeve that surrounds a joint and provides protection and stabilization


a projection or bump of the skeleton

Growth Hormone

anterior pituitary hormone that stimulates tissu egrowth and anabolism when nutrients are abundant and restricts tissue glucose dependence when nutrients are in short supply


the lateral, relatively small leg bone


a groove or furrow

Vertebral Canal

Passageway that encloses the spinal cord, a tunnel bounded by vertebral arches of adjacent vertebrae
