What is the diaphysis? --- correct answer --- -shaft of a long bone
What is the medullary cavity? --- correct answer --- -hollow chamber in
diaphysis. marrow fills this
cavity
What is the periosteum? --- correct answer --- -a dense layer of vascular
connective tissue enclosing a bone
what is compact bone? --- correct answer --- -wall of the diaphysis mainly
composed of tightly packed tissue
what is spongy bone? --- correct answer --- -cancellous bone that largely
composes the epiphysis
Describe the process of ossification --- correct answer --- -step one 1:
cordlike and connects muscles to bones; a broad sheet of dense
connective
tissue that connects muscles to
muscles
step 2: Long bones develop from rods of cartilage, some from membranes
and some from tendons.
,step 3: Ossification occurs first in the cartilage rods, then in the epiphyses
of long
bones.
step 4: When the epiphysial cartilage has ossified (hardened), bone growth
stops.
What is the epiphyseal plate? --- correct answer --- -as spongy bone is
deposited in the diaphysis and in the epiphysis, a band of cartilage will
form
what are osteoclasts? --- correct answer --- -cells that break down bone
what are osteoblasts? --- correct answer --- -bone forming cells
what are the functions of the skeletal system? --- correct answer --- -
support,
movement, storage, blood cell formation
protection,
What is the axial skeleton? --- correct answer --- -skull, vertebral column,
rib cage
What is the appendicular skeleton? --- correct answer --- -pectoral girdle,
upper limbs, pelvic girdle, lower limbs
what are the parts of a long bone? --- correct answer --- -epiphysis and
diaphysis
,What is the epiphysis? --- correct answer --- -end of a long bone that
articulates (forms a joint) with another bone.
what are the steps of fracture repair? --- correct answer --- -1. Hematoma
formation- blood vessels, tissues in broken bone are torn resulting in a
Hematoma mass of clotted cells. Bone cells with no nutrition will die and
area will become irritated.
Fibrocartilaginous callus formation- phagocytic cells invade the
2.
area and begin cleaning up the debris.
Bone callus formation- about 1 week into repair, new bone begins to
3.
repair. This is called a bony callus. This continues for about 3 months.
Bone remodeling- excess material removed, shaft was reconstructed.
4.
how are bones classified? --- correct answer --- -by shape
what are the shapes of bones? --- correct answer --- -long, short, flat,
irregular
example of long bone --- correct answer --- -femur
example of short bones are --- correct answer --- -carpals and tarsals in the
ankle and wrist
, examples of flat bones --- correct answer --- -ribs, scapulae, and some bones
of the skull
examples of irregular bones --- correct answer --- -facial bones, vertebrae
What is articular cartilage? --- correct answer --- -hyaline cartilage
covering
articular ends of the
bones
What is a joint capsule? --- correct answer --- -tissue that stops synovial
fluid from escaping and encloses and supports and holds the bones
together.
what is a ligament? --- correct answer --- -Connects bone to bone and
reinforce the joint capsule.
What is the synovial membrane? --- correct answer --- -inner layer of the
joint capsule, covers all of the surface within the joint capsule.
What is synovial fluid? --- correct answer --- -Lubricates and nourishes the
cartilage covering the bones at movable joints and contains macrophages
the remove microbes and debris from the joint cavity.
what is the menisci? --- correct answer --- -cushion the articulating
surfaces
and help distribute body weight onto these surfaces
