The human skeleton is made up of how many bones?
206
What are the primary functions of bones?
Primary organs of the skeletal system. Composed of 50% water and 50% solid matter.
Provide shape, support, and the framework of the body.
Provide protection for internal organs.
Play an important role in the formation of blood cells (hematopoiesis)
Provide areas for the attachment of skeletal muscles.
Help make movement possible through articulation.
Primary function of cartilage?
Forms the major portion of the embryonic skeleton and part of the skeleton in adults.
Primary function of tendons?
Attach muscles to bones, consist of connective tissue.
Ligaments (lig)
Bands of fibrous connective tissue that connect bones, cartilage, and other structures; also serve as a place for attachment of fascia.
Osseous tissue
The solid matter in bones that is calcified and rigid.
Matrix
The intracellular substance of bone that makes up the osteosarcoma tissue.
What are the classifications of bones?
Flat, long, short, irregular, sesamoid, sutural or wormian.
Flat bones
Ribs, scapula parts of the pelvic girdle, bones of the skull.
Long bones
Tibia, femur, humerous, radius
Short bones
Carpals, tarsals
Irregular bones
Vertebrae, ossicles of the ear.
Sesamoid bones
Patella
Sutural or Wormian
Between the flat bones of the skull.
Osteoblasts
Bone-forming cells
Endochondral ossification
The process where bone cells deposit organic substances in the spaces vacated by cartilage to form bone matrix.
Epiphysis
The ends of developing bone.
Diaphysis
The shaft of a long bone.
Periosteum
The fibrous vascular membrane that forms the covering of bones except at their articular surfaces.
Compact bone
The dense, hard layer of bone tissue.
Medullary canal
The narrow space or cavity throughout the length of the diaphysis.
Endosteum
A tough, connective tissue membrane lining the medullary canal and containing the bone marrow.
Cancellous or spongy bone
The reticular network that makes up most of the volume of bone.
Epiphyseal plate
Also known as the growth plate or physics. It is a thin disc of hyaline cartilage positioned between the epiphysis and diaphysis. Once growth is complete this becomes the epiphyseal line.
Joint (jt)
Is the place where two or more bones connect.
The three classifications of joints?
Synarthrosis (fibrous), amphiarthrosis (cartilaginous), and diarthrosis (synovial)
Synarthrosis (fibrous)
Does not permit movement. The bones are in close contact with each other, but there is no joint activity. Ex. Cranial suture
Amphiarthrosis (cartilaginous)
Permits very slight movement. Ex. Vertebra
Diarthrosis (synovial)
Allows free movement in a variety of directions. Ex. Knee, hip, elbow, wrist, foot.
Flexion
Bending a limb.
Extension
Straightening a flexed limb.
Circumduction
Moving a body part in a circular motion.
Abduction
Moving a body part away from the middle.
Adduction
Moving a body part toward the middle.
Protraction
Moving a body part forward.
Retraction
Moving a body part backward.
Dorsiflexion
Bending a body part backward.
Plantarflexion
Moving a body part away from you
Pronation
Lying face downward, also turning the palm downward.
Supination
Lying face upward and also turning the palm or foot upward.
Cervical curve
Consists of the first 7 vertebrae.
Thoracic curve
Consists of the next 12 vertebrae.
Lumbar curve
Consists of the next 5 vertebrae.
Sacral curve
Consists of the sacrum and coccyx.
Lumbar lordosis
This happens in children who are beginning to walk and have a pot-bellied stance. A posture that usually disappears around age 5.
Pelvic differences.
A male pelvis (android) has a more narrow outlet than a female pelvis (gynecoid), due to a male not giving birth. The male pelvis is shaped like a funnel and a female more like a basin.
Closed or simple fracture
A completely internal break that does not involve a break in the skin.
Open or compound fracture
The fracture projects through the skin and there is a possibility of infection or hemorrhage.
Greenstick fracture
Only one side of the shaft is broken, and the other side is bent. This usually occurs in children whose long bones have not fully ossified.
Colles’ fracture
A break in the distal portion of the radius. Often a result of reaching out to cushion a fall.
Pott’s fracture
Occurs at the ankle and affects both bones of the lower leg. (fibula and tibia)
Ankylosis
Abnormal condition of stiffening of the joint.
Arthralgia
Joint pain
Arthrocentesis
Surgical procedure to remove joint fluid; may be used as a diagnostic tool or as part of a treatment plan
Arthroscope
Surgical instrument used to examine the interior of a joint.
Bursitis
Inflammation of a bursa.
Calcaneal
Pertaining to the heel bone.
Carpal
Pertaining to the wrist bones. There are two rows of four bones for a total of eight wrist bones.
Carpel tunnel syndrome
Abnormal condition caused by compression of the median nerve by the carpal ligament due to injury or trauma to the area.
Cartilage
Specialized type of fibrous connective tissue found at the ends of bone. Forms the major portions of the embryonic skeleton before birth.
Chondral
Pertaining to cartilage.
Coccygeal
Pertaining to the coccyx or tail bone.
Costal
Pertaining to the rib.
Dactylogram
Medical term for fingerprint.
Fixation
Process of holding or fastening in a fixed position; making rigid, immobilizing.
Genu valgum
Medical term for knock-knee.
Gout
Hereditary metabolic disease that is a form of acute arthritis, which is marked by joint inflammation. It is caused by hyperuricemia. (Excessive amounts of uric acid in the blood and deposits of urates of sodium) in and around the joints. It usually affect the great toe first, but can be seen in the finger, knee, elbow or foot joints.
Hallux
Medical term for the big or great toe.
Intercostals
Pertaining to the space between two ribs.
Kyphosis
Condition in which the normal thoracic curvature becomes exaggerated, producing a “humpback” appearance.
Ligament (lig)
Band of fibrous connective tissue that connects bones, cartilage, and other structures; also serves as a place for the attachment of fascia.
