midterm anaphy Flashcards
- red bone marrow produce red blood cells, hematopoiesis produce white blood cells and platelets
blood cell production
- distal and proximal ends of the bone
epiphysis
- provides structural framework and shape, supporting soft tissues, provides attachment of most skeletal muscles
support
- hollow space within the diaphysis– contains yellow bone marrow
medullary cavity
contains haversian canal, contains blood vessels, nerve and lymphatic vessels
haversian system
- does not contain osteons
- red bone marrow is present
spongy bone
- bone forms within hyaline cartilage, that develops from mesenchyme
endochondral ossification
- projections that form joints and attachment points for connective tissue
processes
- bone forms directly within loose fibrous connective tissue (mesenchyme) arranged in sheetlike layers that resemble membranes
intramembranous ossification
- bone tissue stores calcium and phosphorus, releases minerals into the blood to maintain homeostasis
mineral growth factor stage
- nearly equal length and width, wrist and ankle bones
short
- complex shapes, vertebrae, some facial bones
irregular
- skeleton protects many internal organs from injury
protection
- main cells of bone tissue, and maintain its daily metabolism, does not undergo cell division
osteocytes
- thin layer of hyaline cartilage, reduces friction and absorbs shock at freely movable joints– articulation
aricular cartilage
- generally thin, provide protection
flat
- thin membrane that lines the medullary cavity– contains 1 layer of bone-forming cells
endosteum
enumerate the bone structure
diaphysis, medullary cavity, endosteum, epiphysis, epiphyseal plate, epiphyseal line
enumerate bone surface markings
depression/openings, processes
- contains few spaces, arranged in repeating units
compact bone
- protects the bone, assists in fracture repair, anchors tendons and ligaments
periosteum
- separates diaphysis and epiphysis– region of mitosis
epiphyseal plate
- replaces epiphysial plate when bone growth is completed
epiphyseal line
stores calcium & phosphorus, releases minerals into the blood to maintain homeostasis
bone tissue
factors that affect bone growth
heredity, nutrition, hormones, exercise/stress
- red bone marrow produce red blood cells, hematopoiesis produce white blood cells and platelets
blood cell production
- process by which bone forms
- occurs in 6th/7th week of embryonic dev’t
ossification
enumerate bone classification
long, short, flat, irregular
- form joints/ allow passage of blood vessels, nerves, ligaments, tendons
depression/openings
arranged in sheetlike layers that resemble membranes
mesenchyme
- have greater length and width, consists of shaft
long
- skeletal muscle attached to bones, when muscle contract. they pull bones
assisting in movement
- bones shaft/body, long, cylindrical main portion of the bone
diaphysis
- forms longitudinal axis of the body
axial
- consists of cranial bones & facial bones
skull
- immovable joints between bones of the skull
sutures
- spaces between cranial bones of fetus + infants
fontanels
(coronal, sagittal, lambdoid, squamous)
sultures
- (anterior, posterior, anterolateral, posterolateral)
fontanels
- cavities in bones (skull) that communicate with nasal cavity
paranasal sinuses
- transmit vibrations (malleus, incus, stapes)
ear ossicles
- u-shaped bone that does not articulate with any bone
- support tongue and neck muscle
hyoid bone
- contains normal curves that gives strength, support + balance, protects spinal cord
vertebral column
- 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacrum/coccyx
vertebral column
- protects organs and thoracic cavity
rib cage
- manubrium, body, xiphoid process
sternum
(first 7 pairs) articulate with sternum by mean of costal cartilages
true ribs
(next three pairs) articulate with 7th costal cartilages
false ribs
(last two pairs) do not articulate with the sternum
floating ribs
80 skeleton
axial
126 skeleton
appendicular
126 skeleton
appendicular
consist bones of the girdles + upper, lower extremidies (limbs)
appendicular
- attach upper limbs to the axial skeleton
pectoral girdle
clavicles
collar bone
scapulae
shoulder blade
- 30 bones in each (left & right)
upper limb
- articulates with scapula, ulna (elbow), radius (forearm), carpals (wrist), metacarpals (hand), phalanges (fingers)
humerus
point of fusion
acetabulum
- connects lower limbs to axial skeleton, each hip bone: ilium, ischium, pubis (fused)
pelvic girdle
- thigh, largest, longest, strongest bone in the body
femur
- triangular bone
patella
- medial side of the leg
tibia
- lateral side of libia
fibula
- ankle
tarsals
foot
metatarsals
- toes
phalanges
- toes
phalanges
- aka articulations
- point of contact between 2 bones
joints
- immovable
synarthroses
- slightly movable
b. amphiarthroses
- freely movable
diarthroses
- no joint cavity
- bones are held together by fibrous connective tissue
fibrous
- no joint cavity
- bones are held together by cartilage
b. cartilaginous
- contains synovial cavity, articular cartilage, joint capsule, synovial bursae membranes
synovial
- flat bones move side to side
gliding
- flexion– extension, abduction– adduction, circumduction
angular
- bone moves around its own longitude axis
rotation
- joints between carpals & tarsals
plane
- elbow & knee
hinge
- radius & ulna
pivot
- metacarpals & carpals
candyloid
- thumb metacarpal
saddle
- shoulder & hip
ball & sacket
