48 Cards in this Set

  • Front
  • Back
Rounded depression, or socket, in the pelvis, which joins the femur (thigh bone), forming the hip joint
acetabulum
Outward extension of the shoulder bone forming the point of the shoulder. It overlies the shoulder joint and articulates with the clavicle.
Acromion
Thin layer of cartilage occurring at the ends of long bones and covering any part of any bone that comes together with another bone to form a joint.
articular cartilage
Dense, hard connective tissue composing the skeleton. Examples are long bones (femur), short bones (carpals), flat bones (scapula), and sesamoid bones (patella).
Bone
One of the mineral constituents of bone. Calcium phosphate is the major calcium salt in bones.
Calcium
Spongy, porous, trabecular bone.
Cancellous bone
Flexible, rubbery connective tissue. It is found in the immature skeleton at the epiphyseal growth plate and on joint surfaces.
cartilaginous tissue (cartilage)
Dense connective tissue strands found in bone.
Collagen
Hard, dense bone tissue.
Compact bone
Knuckle-like process at the end of a bone near the joint.
Condyle
Skull bones; ethmoid, frontal, occipital, parietal, sphenoid, and temporal.
Cranial bones
Shaft, or midportion, of a long bone.
Diaphysis
Flat, round, plate-like structure. An intervertebral disk is a fibrocartilaginous substance between two vertebrae.
disk (disc)
Cartilaginous area at the ends of long bones where lengthwise growth takes place in the immature skeleton.
Epiphyseal plate
Each end of a long bone; the area beyond the epiphyseal plate.
Epiphysis
Bones of the face: lacrimal, mandible, maxillae, nasal, vomer, and zygomatic.
Facial bones
Narrow, slit-like opening in or between bones.
Fissure
Soft spot (incomplete bone formation) between the skull bones of an infant.
Fontanelle
Opening or passage in bones where blood vessels, nerves, or both enter and leave. The foramen magnum is the opening of the occipital bone through which the spinal cord passes.
foramen
Shallow cavity in a bone.
Fossa
Minute spaces filled with blood vessels; found in compact bone.
Haversian canals
Round process on both sides of the ankle joint. The lateral malleolus is part of the fibula, and the medial malleolus is part of the tibia.
Malleolus
Upper portion of the sternum; articulates with the medial aspect of the clavicle.
Manubrium
Round projection on the temporal bone behind the ear.
Mastoid process
Central, hollowed-out area in the shaft of a long bone.
Medullary cavity
The flared portion of a long bone, lying between the diaphysis (shaft) and the epiphyseal plate (meta- means between)
metaphysis
Large process on the proximal end of the ulna; the point of the flexed elbow.
Olecranon
Bone tissue.
Osseous tissue
Process of bone formation.
ossification
Bone cell that helps form bone tissue.
Osteoblast
Bone cell that absorbs and removes unwanted bone tissue.
Osteoclast
Membrane surrounding bones; rich in blood vessels and nerve tissue.
periosteum
Mineral substance found in bones in combination with calcium.
Phosphorus
Area of confluence (coming together) of the two pubic bones. They are joined (sym-means together, -physis means to grow) by a fibrocartilaginous disc.
Pubic symphysis
Found in cancellous bone; site of hematopoiesis.
Red bone marrow
These 24 elongated, curved bones form the bony wall of the chest. True ribs are the first 7 pairs; false ribs are pairs 8-10; floating ribs are pairs 11 and 12.
Ribs
Depression in the sphenoid bone where the pituitary gland is located.
Sella turcica
Hollow cavity within a bone.
Sinus
Pole-like process on the temporal bone.
Styloid process
Joint between bones, such as the skull (cranium).
Suture
Connection between the temporal base of the skull and mandibular bone of the jaw.
temporomandibular joint
Supporting bondles of bony fibers in cancellous (spongy) bone
Trabeculae
Large process on lateral proximal aspect of the femur; attachment site for muscles and tendons.
Trochanter
Rounded process on bone; attachment site for muscles and tendons.
Tubercle
Rounded process on bone; attachment site for muscles and tendons.
Tuberosity
An individual backbone composed of the vertebral body, vertebral arch, spinous process, transverse process, lamina, and neural canal.
Vertebra
Lower, narrow portion of the sternum.
Xiphoid process
Fatty tissue found in the diaphyses of long bones in older individuals.
Yellow bone marrow
