synovial membrane, synovial fluid
crooked, bent, stiff
to bind, tie together
curve, swayback, bent
loosening or setting free
vertebrae, vertebrae column, backbone
axial skeleton VS. appendicular skeleton
-protects the nervous, respiratory, circulatory system
: skull, ossicles of middle ear, the hyoid bone, rib cage, vertebral column.
-makes body movement possible
-protects the organs digestion, excretion, and reproduction.
: upper extremities (shoulders, arms, forearms, wrists, and hands), lower extremities (hips, thighs, legs, ankles, and feet)
What are the functions of the skeletal system?
-protect/support internal organ
-work together with muscles
-Red Bone Marrow to formation of RBCs
-storage of calcium in marrow
What are the structures of the muscular system?
-# of divisions
tough, firbrous tissue that forms the
of the bone
Compact Bone (cortical bone)
dense, hard, and very strong bone that forms the
PROTECTIVE OUTER LAYER
of the bone.
Spongy Bone (cancellous bone)
lighter and not as strong as compact bone; found at the ends and inner portions of LONG BONES (femur).
Location of red bone marrow production.*
located in the SHAFT OF THE LONG BONES where it is surrounded by compact bone.
*Yellow bone marrow is stored in this cavity*
tissue that lines the medullary cavity.
Red bone marrow
located in the spongy bone (femur)
is the hemopoietic tissue that produces RBC, WBC, thrombocytes, hemoglobin.
Yellow bone marrow
functions as fat storage area.
located in the medullary cavity of long bones.
What is hemopoietic process?
PT to the formation of blood cells.
What are the three types of cartilage?
blue/white & smooth rubbery CT
L:outer ear/nose tip
F:protects bones from friction and facilitates smooth movement.
L:some joints of the knee & jaw
F:shock absorber between bones
shaft of the long bone
wider ends of the long bone (i.e. femur)
opening in a bone through which blood vessels, nerves, and ligaments pass.
normal projection that serves as an attachment for a muscle or tendon.
What are the three types of joints?
: flexible dense CT (sutures; fontanelles-baby soft spots)
: slight movement, connection of bones (ribs, pubic symphysis)
: between two bones to allow variety of motions (ball & socket, hinge)
What are the components of synovial joints?
Fibrous sac lined with synovial membrane and stores synovial fluid.
: shoulder, knee, elbow
: cushion to prevent friction
fibrous tissue that connect bone to bone
: many areas
: provides movement
surrounded by fibrous capsule and lined with synovial mem.
: lubricant and allows smooth movements of the joints.
C1-C7; form the neck.
T1-T12; has rib bones connected to form the outward curve of the spine.
L1-L5; form the inward the inward curve of lower spine.
loss or absence of mobility in a joint due to disease, injury, or surgical procedure.
partial displacement of a bone from its joint.
total displacement of a bone from its joint.
when the bone is pressed together on itself.
known as a fractured wrist
bone is broken but there is no open wound in the skin
bone has broken through the skin
bone is splintered and crushed.
bone is is bent and partially broken.
bone has twisted apart
means originating within another. Retrieving a transplant from a compatible donor.
means originating within individual. Patient retrieves their own transplant that has been harvested, stored away.
broken bone due to disease such as osteoporosis.
mechanical appliance to support broken bone. i.e. cast or leg brace.
also known as open reduction internal fixation. FRACTURE TREATMENT in which a plate or pins are placed directly into the bone to hold the broken pieces in place.
