Trabecula

A connective tissue partition that subdivides an organ

Ischium

One of three bones who fusion creates the coxa

External Acoustic Canal

Passageway in the temporal bone that leads to the tympanum

Forearm

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

Estrogens

A class of steroid sex hormones that includes estradiol

Meniscus

A fibrocartilage pad between opposing surfaces in a joint

Carpus/Carpal

the wrist

Elevation

movement in a superior, or upward direction

Tendon

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

Eversion

a turning outward

Periosteum

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

Coccyx

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

Capitulum

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

Osteoclast

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

Symphysis

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

Arthritis

inflammation of a joint

Tubercle

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

Ilium

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

Fracture

a break or crack in the bone

Pubic Symphysis

Fibrocartilaginous amphiarthrosis between the pubic bones of the ossa coxae

Dorsiflexion

Elevation of the superior surface of the foot

Osteocyte

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

Amphiarthrosis

an articulation that permits a small amount of movement

Abduction

movement away from the midline

Calcaneus

the heelbone, largest of the tarsal bones

Fossa

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

Pedicles

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

Sole

inferior surface of the foot

Calcitonin

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

Marrow

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

Pubis

the anterior, inferior component of the os coxae

Depression

inferior (downward) movement of a body part

epiphysis

head of a long bone

Metatarsal

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

inversion

a turning inward

Tuberosity

a large, roughened elevation on a bony surface

Condyle

a rounded articular projection on the surface of the bone

Fontanel

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

Flexion

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

Bursa

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

Supination

rotation of the forearm such that the palm faces anteriorly

Cancellous bone

spongy bone, composed of a network of bony struts

Phalanx/Phalanges

bone of the finger or toes

White blood cells

Leukocytes; the granulocytes and agranulocytes of the blood

Trunk

the thoracic and abdominopelvic regions

Osteon

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

Circumduction

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

Contractility

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

Process

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

Fibula

the lateral, relatively small leg bone

Sulcus

a groove or furrow

Vertebral Canal

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