Q

what does skeleton provide

A

-support, movement, and protection from vital organs
(ex: skull protects the brain, rib cage protects the lung and heart, vertebral column protects the spine)

Q

What are the 5 main function of the skeleton

A

-Structural support-soft tissue (muscle and internal organs)
-Protection- delicate parts of the body
-Cell growth center- red blood cells platelets
-Mineral reservoir- regulation of phosphate and calcium
-Movement- Muscle contract move bone

23
what the are 5 types of bones
-long bones- arms and legs, femur -flat bones- flat ad thin, parietal bone -irregular bones- odd-looking, vertebrae -sesamoid bones- unusual, small, flat wrapped within tendons, move over bony surface, and patella -Short bones- wrists, ankles, and carpal bones -
24
axial skeleton
-80 bones -vertebral column, skull, ribcage -Vertebrae of the spine protects the spinal chord, cranium protects the brain, ribcage protects the lungs and the heart -face, tongue, neck, muscles, for mastication and drinking, muscles around vertebrae of the spine -core muscle provides stability and support -Respect to appendicular skeleton
25
Appendicular skeleton
-126 bones -moveable limbs and gridles -upper limbs- attach to the shoulder girdle -lower limbs- attach to the pelvic girdle -pectoral girdle- two scapulae and two clavicle -humerus- attach at glenoid cavity -Pelvic girdle- has two hip bones (hip bones and sacrum makes ring of the pelvis) -acetabulum cavity- fused bones meets -six major regions: .pectoral girdle(4 bones)- left and right clavicles and scapula .arms and forearms(6 bones)- left and right humerus, ulna, and radius .hands(54 bones)- left and right carpals, metacarpals, proximal phalanges, intermediate phalanges, and distal phalanges .Pelvis(2bones)- left and right hip bones .thighs and legs(8 bones)- left and right femur, fibula, patella, tibia and fibula .feet and phalanges(52 bones)- left and right tarsals, metatarsals, proximal phalanges, intermediate phalanges, and distal phalanges -Bone landmarks: .passage of blood vessels and nerves .attachment of ligaments, tendons, and muscles
26
Different types of Fractures
-Simple fractures: No separation of the bone Break/crack Hairline fracture Greenstick fracture -Compound fracture: Separation to pieces Transverse fracture Major blow -Comminuted fracture Broken ends shattered to pieces Major automobile accident
27
Stress fracture and shin splints
-Stress fracture: Fragile muscles transfer impact to bone Rapid increase in activity -Shin splints: Overuse Medial/lateral side of tibia Untreated leads to shin splints
28
Aging on the skeletal system (osteoporosis)
-Low bone mass -Deterioration of bone tissue -Fragile bone -Vertebrae collapses -Defenses: Build strong bones at early age balanced diet weight bearing exercise healthy lifestyle bone density and medication
29
Types of human joint
-Fibrous- no movement, connected by connective tissue -Cartilaginous- cartilage(flexible tissue), slight movement, intervertebral discs of spinal column -Synovial- most movement between 2 or more bones, common, distinguished by movement, ball and socket, gliding/plane, hinge, pivot, saddle, ellipsoid
30
Types of synovial joint
-Ball and socket- most moveable, ball at one ball fits into the socket of another, multi axial -Gliding- flat/curved bone surface -hinge- uni-axial, bones fit together -Pivot- round point of a bone fits into the groove of another, uni-axial rotation -Sattle- bi-axial, bones fit together -Ellipsoid-bi-axial
31
Osteoarthritis
-Loss of cartilage at bone -Joint disease -Old people, athletes, and women -hips, knees, and fingers
32
bursitis
-Inflammation of bursae -Friction between tendons, ligaments, and bones
33
Wear and tear
34
Cartilage
-torn in cartilage(common in knees) -sports with lateral movement/contact
35
athroscopy
-Surgical procedure
36
Ligaments
-attach bones together -less rigid than bones
37
sprain
-Ligaments is overstretched -First degree- stretch -Second degree- tear -Third degree- severe -Treatment: pressure, ice, elevate, rest
38
Dislocation
-Bone is displaced from the joint -collision/fall -finger/shoulder -medical help/surgery
39
Separation
-Connecting tissue instead of bone being displaces -Collision/fall -Shoulder separation
40
Articular cartilage-synovial Joint
-smooth surface contact -Reduce friction -Ends of the two bones meet
41
blood vessel-synovial joint
-Gives nutrients -Removes waste
42
Bone-synovial joint
43
Bursae-synovial joint
-fluid at friction points between tendons, ligaments, and bones
44
Joint capsule-synovial joint
-protected by strong fibers -outer structure -passage of the nutrients throughout the joint
45
Joint cavity-synovial joint
-space between the joint -synovial fluid provides nutrients and reduce friction
46
Nerve-synovial joint
-sends and receives message to the brain
47
Synovial membrane-synovial joint
48
Tendons-synovial joint
-Muscle attach to the bone
49
Periosteum-synovial joint
-Outside lining -Connects to the tendons
50
Ligaments-synovial joint
-Prevent bone dislocation -two bones are connected -thickens and reinforce joint capsule -fibrous tissue
51
Cartilage-long bone
-articulating cartilage -smooth movements and provides nutrients -no blood supply/nerve ending
52
Cancellous bone-long bone
-Filled with marrow -strengthen with strength exercise
53
Compact bone-long bone
-Dense -Structural integrity
54
diaphysis-long bone
-thickest part
55
Epiphyseal line-long bone
56
Epiphyseal plate-long bone
-located everywhere
57
Epiphysis-long bone
-made of compact bone -articulates with bone is filled with cartilage
58
Medullary cavity-long bone
-Red bone marrow: formation of red-blood cells -Yellow bone marrow: Filled with fat -Inside shaft -No connective tissue
59
Periosteum-long bone
-connective tissue covering the bone -Connect bone to muscle and vice versa
60
Cortex-long bone
-Outside: Fibers -Inside: Bone marrow
