Q

Compact bone tissue

A

strongest type of bone tissue; makes up bulk of diaphysis
found beneath peristoneum of all bones
provides support, protection and resistance against stresses produced by weight and movement

Q

Spongy bone tissue

Study These Flashcards
A

light tissue found in flat and irregular shaped bones and forms most of epiphysis of long bones
does NOT contain osteons
consists of trabeculae

23
Q

Trabeculae

Study These Flashcards
A

found in spongy bone tissue; irregular latticework of bone consisting of lamellae, osteocytes and canaliculi.
spaces btw trabeculae are filled with red bone marrow

24
Q

Ossification

Study These Flashcards
A

bone formation

25
Mesenchyme cells
all tissues develop from these embryonic connective tissue cells
26
human growth hormone (hGH)
1/4 hormones important for bone growth and maintenance; stimulates bone growth by stimulating production of IGFs
27
Insulin-like growth hormones (IGFs)
1/4 hormones important for bone growth and maintenance; produced by liver in response to hGH stimulation; stimulates osteoblasts promoting normal bone growth
28
Thyroid hormone
1/4 hormones important for bone growth and maintenance; stimulate normal bone growth by stimulating osteoblasts; secreted by thyroid hormone
29
Insulin
1/4 hormones important for bone growth and maintenance; secreted by pancreas; increases synthesis of bone proteins to promote normal bone growth.
30
Parathyroid Hormone
promotes bone resorption by osteoclasts; enhances recovery of calcium ions from urine and promotes formation of calcitriol
31
Calcitonin
secreted by thyroid; inhibits bone resorption by osteoclasts
32
Osteoperosis
when bone destruction outpaces bone deposition the bone becomes porous and weak and prone to fracture
33
Foramen
hole through which blood vessels, nerves and ligaments pass
34
Foramen Magnum
hole in occipital bone where spinal cord connects to medulla of brain
35
Fossa
shallow depression in/on the bone; ie. pituitary gland sits in a fossa on the sphenoid bone
36
Facet
flat, smooth process that extends from a bone to form a joint; found on the vertebrae
37
Process
a projection that is used for the attachment of tendons, ligaments, and other connective tissue
38
Joints
connect bone to bone, cartilage to bone or teeth to bone
39
Synarthrosis
an immoveable joint; permits little to no movement
40
Amphiarthroses
slightly moveable joint; ie. suture in children
41
Diarthroses
freely moveable joints; all synovial joints are diarthroses
42
Ligaments
main mechanical factor that hold bones close together in synovial joint
43
Synovial Fluid
secreted by synovial membrane of articular capsule in synovial joints; consists of hyaluronic acid and acts to reduce friction (by lubricating) and supply nutrients/remove waste
44
Menisci
within synovial joints; modifies joint surface allowing bones of different shapes to fit tightly this helps to maintain stability of joint and also directs flow of synovial fluid to areas of greater friction
45
Bursae
fluid filled sacs that cushion movement of one body part over another; bone between skin and bone where skin rubs over the bone, also between tendons and bone, muscle and bone and ligaments and bone
46
Medial and Lateral Collateral Ligaments
accessory ligament of the knee; in place to stop knee from slipping to far right/left (ligaments join bone to bone)
47
Anterior and Cruciate Ligaments
two innermost crisscrossing ligaments of the knee; prevents knee from slipping forward and backward
48
Patella
the kneecap; acts as a floating bone shield to protect knee from anterior (Front) blows
49
Oblique Popliteal Ligament
accessory ligaments of the knee; strengthens posterior (back) surface of joint
50
Arcuate popliteal ligament
accessory ligament of the knee joint; strengthens lower lateral (side) part of the posterior (back) surface of joint
51
Fat Pads
accessory structure of knee joint; protects the knee
52
Bursa
accessory structure of knee joint; fluid-filled bags; protects the knee
53
Synovial membrane
inner most membrane of knee joint (synovial joints); keeps whole joint isolated; found within an outer fibrous capsule
