Skeletal Flashcards
The point at which the clavicle attaches to the acromion process.
acromioclavicular (AC) joint
An injury caused by distraction of the clavicle away form the acromion process of the scapula.
Acromioclavicular (AC) separation
The tip of the shoulder and the site of attachment for both the clavicle and shoulder musculature.
acromion process
The ridges between the teeth, which are covered with thickened connective tissue and epithelium; also called aveolar ridges.
alveolar arch
A ring of fibrous or fibrocartilaginous tissue that is part of the intervertebal disk.
anulus fibrosus
The portion of the skeletal system that comprises the arms, legs, pelvis, and shoulder girdle.
appendicular skeleton
The formation of new bone on the surface of a bone.
appositional growth.
The first cervical (C1), which provides support for the head.
atlas
The part of the skeleton comprising the skull, spinal column, and rib cage.
axial skeleton
The second cervical vertebra, the point that allows the head to turn.
axis
Bruising over the mastoid process, usually from a basilar skull fracture.
Battle sign
Specialized tissue found within bone that manufactures most erythrocytes.
bone marrow
Grinding together of the upper and lower teeth.
bruxism
A ballooning of an intervertebral disk without frank herniation.
bulging disk
Small fluid-filled sacs located between a tendon and a bone help lubricate two surfaces that are rubbing against each other.
bursae
The heel bone.
calcaneus
The zone of repair in which a mass of exudates and connective tissue forms around a break in a bone and converts to bone during healing.
callus
A minute canal in a bone.
canaliculi
Bone that is made up of a lacy network of bony rods called trabeculae.
cancellous bone
compression of the median nerve within the carpel canal at the wrist.
carpal tunnel syndrome (CTS)
The bones of the wrist; also forms they include the scaphoid, lunate, trequetrum, pisiformm, trapezium, trapezoid, capitate, and hamate bones.
carpals
The support structure of the skeletal system that provides cushioning between bones; also forms the nasal septum and portions of the outer ear.
cartilage
The most serious disk rupture that occurs when nuclear material protrudes straight back into the spinal canal, potentially compressing neurologic elements and causing neurologic injury.
central disk herniation
fluid produced in the ventricles of the brain that flows in the subarachnoid space and bathes the meninges.
cerebrospinal fluid (CSF)
The seven smallest vertebrae, found in the neck.
cervical vertebrae
Cells that produce cartilage.
chondroblasts
The collarbone; it is lateral to the sternum and anterior to the scapula.
clavicle
cells that produce cartilage.
chondroblasts
The collarbone; it is lateral to the sternum and anterior to the scapula.
clavicle
A fracture in which the bone; ends have not been exposed by a break through the skin.
closed fracture
The tailbone
coccyx
Bone that is mostly solid, with few spaces.
compact bone
A fracture of a vertebral body associated with collapse of the body.
compression fracture
The point where the parietal bones join together with the frontal bone.
coronal suture
Inflammation of the costal cartilage, which attaches the ribs to the sternum.
costochondritis
The point where the parietal bones join together with the frontal bone.
coronal suture
The bones that encase and protect the brain, including, the parietal, temporal, frontal, occipital, sphenoid, and ethmoid bone.
cranium
A grinding sound or sensation.
crepitus
Horizontal bones perforated with numerous foramina for the passage of the olfactory nerve filaments from the nasal cavity.
cribriform plates
A progression form of arthritis that causess deterioration of the intervertebral disk.
degenerative disk disease
The shaft of a long bone.
diaphysis
A fracture in which bone fragments are separated from one another and are not in anatomic alignment.
displaced fracture
A state of abnormally small bones.
dwarfism
The growth of cartilage in the physis (epiphyseal plate) which is eventually replaced by bone.
endochondral growth
A layer that lines the inner surfaces of bone.
endosteum
An inflammation of the muscles of the elbow joint; it also forms part of the eye orbits.
epicondylitis
