4 general features of intramembranous bone formation: *occurs in flat bones of skull clavicles, *begins with collagenous fiber membran, *membrane is compact bone amd *fontanels (soft spot) not yet ossified
a hip joint is an example of___ and a knee joint is an example of: ball and socet & hindge joint
a rigid rid that moves about a fixed point led zeppelin song: a lever
bones as levers a lever and a fulcrum are (fulcrum is an example of what) smoke it: a rigid rod that moves about a ficedpoint and fulcrum is the fixed point around with a lever moves (joint)
fractures and their repair defenition, and tyes: defenition is any break in a bon, may take months to repair and types include simple, compound, greenstick, spiral comminuted
spongu bone dense bone: cancellous
compact
a "collar of bone is produced around what?: the diaphysis or shaft
a greenstick fracture is when the: shaft is bent or broken
a spiral fracture is when bone is a: twisting force, ragged break
an action potential is: a migrating region of membranepotential reversal
articulations classified by__ fibrous joint_sutures of skull. Cartilagenous joint_pubic symphysis and synovial joint_knee: structure
Bone cells three types: osteoblast osteocytes and osteoclasts
bony callus in fracture repair is remodeled by what bone cell: osteoclasts
cartilage is replaced by bone except at articular surfaces under what process: formation of secondary center of ossification for endochondral bone formation
cartilage model is covered by perichondruim and perichondrum becomes periosteum: formation of bone collar under endochondral bone formation
chondrocytes die under what process (think too much milk): calcification of diaphyseal cartilage
comminuted fracture is when bone is: shattered into fragments
compound fracture is where the: bone protrudes through skin
contraction of muslce is controlled by MMSMF F: motor areas of cerebral cortex, motor neurons, synapses, muslce fibers and feedback to brain
CT cells cluster and centes of ossification appear: the process of intramembranous bone formation
diffusion is disabled and chondrocytes die under what bone formation: endochondral bone formation under calcification of diaphyseal cartilage
endochondral bone formation: occurs in remainder of skeleto
begins with hyaline cartilage model
cartilage is replaced by bony tissue
formation of bone collar is under what type of bone formation: endochondral bone formation
fulcrum is between the effor/force and the resistance which class is this: first class seesaw and tilting head back
General features of endochondral bone formation: it occurs in remainder of skeleton, begins with hyaline cartilage and cartilage is replaced with bony tissue
how fast are repair cells activated, and what cells are the repair cells: osteoblasts and within 48 hours
In fracture repair -broken blood vessels form a fracture (starts with H): hematoma
in fracture repair-ct and capillaries invade site form (FC C): fibrocartilage callus
in muscle tissues, neurotransmitter receptors are located: on the motor end plate
in the intra membranous bone formation what fuses into spongy bone lattice (sounds like me): trabeculae
in the intra membranous bone formation what happens after the lattice is filled with trabeculae: it fills with red bone marrow and thickens into compact bone periosteal ossification
intra-membranous bone formation *occurs in flat bones of skull, *begins with collagenous fiber membrane * membrane calcifies into compact bone *fontanels not yet ossified: fontales are apart of intra membranous bone formation
intramembranous bone formation includes: CT cells cluster & centers of ossification appear, cells differentiate into osteoblasts, osteoblasts secrete a matrix forming trabeculae, calcium salts are deposited
Ivory like, forms outside layer of bone, forms the shaft of long bones. made in the haversian system: compact/ dense bone
lattice fills with red bone marrow and eventually peripheral trabeculae thicken into compact bone: intra membranous bone formation
Long bone, flat bone, short bone, irregular bone: femur, frontal bone, carpals, vertebrae
name 2 things ossification process includes (IE): intramembranous bone formation and endochondral bone formation
name the three phases a muscle twitch undergoes: Lag phase, contraction phase and relaxation phase
name the type of bone formation: CT cells cluster and centers of ossification appear, cells differnetiate into osteoblasts, osteoblast secrete a matrix forming trabeculae and calcium salts deposit: intramembranous bone formation
name this type of bone formation: it occurs in flat bones of skull clavicles, begins with collagenous fiber membrane, the membrane calcifies into compact bone and fontaneles: intamembranous bone formation
nutrient foramen, medullary cavity, epiphysis are all part of a ____bone: long bone humerus and femur
occurs in remainder of skeleto, begins with hyaline cartilage and cartilage is replaced by bony tissue: endochondral bone formation
open spaces, light weight, lattice arrangement and made of microscopic trabeculae subunits. within epiphyses of long bone: Cancellous bone
ossifiaction process includes 2 things: intramembranous bone formation and endochondral bone formation
ossification which is replacement of other tissue with bone has two processes what are they called: intramembranous bone formation and endochondral bone formation
osteoblast: bone cell that secrete to formbone
osteoclasts: bone cells that destroy bone has enzymes that digest protein acids dissolve minerals and forms marrow cavity its involved in remodeling
ostoecytes: mature bone cells that get trapped in osteoblasts
perichondrium becomes periosteum in what formation of what bone: the bone collar
replacement of other tissues with bone is called (starts with an O): ossification
resistanceis between the fulcrum and the effort/force: second class
wheelbarrow and rising up on my toes
skeletal muscle describes muscle by: size (vastus), shape (deltoid), direction of fibers (straight), location (pectoralis chest), number of origins (biceps 2 heads), and action
skin isn;t broken is a what: simple fracture
steps in fracture repair: hematoma, fibrocartilage callu, bone callus and remodeled
sutures: functional synarthrosis and structural fibrous: true
synarthrosis_ immovable joints Amphiarthrosis_slightly mo: FUNCTION
the collar bone is produced where: around the diaphysis
the development of bone begins with what: ossification=replacement of other tissues with bone and begins abouth the 6th week of gestation. size increase until late teens in females
the fixed point around which a lever moves (joints): fulcrum
the knee is functional diarthrosis and structural synovial: true
the pubic symphysis has functional amphiarthrosis and structural cartilagenous: true
the soft spot is what: fontanel and its not yet ossified
the two classifications of skeleton: appendicular and axial
these are what type of joints gliding hinge pivot ellipsodial saddle and ball and socket: synovial knee joints
this class is most common and the effort/force is between the fulcrum and the resistance: third class and most common type in body
flexing the elbow
under what process does cartilage matrix disintegrate: calcification of diaphyseal cartilage in endochondral bone formation
what are repair cells and how soon activated (TV SHOW): osteoblasts and they are activated in about 48 hours
what attaches bones together and are elastic: Ligaments
what attaches muscle to bone, and is inelastic: tendons
what does the spongy bone lattice fill up with: red bone marrow
what element does bone development require: ca2+
what is Hematoma: broken blood vessels that forma a fracture
what lays down bony matrix: osteoblasts
what requires ca2+: bone development under ossification
what surrounds individual fasciles: perimysium
when blood vessels reach epiphyses they are at the: secondary formation center of ossification under endochondral bone formation
when does replacement of other tissue with bone begin? drivers licence: about the 16th week of gestation
where does trabeculae fuse into?: spongy bone lattice
where is the collar bone produced around: the diaphysis
wheredoes cartilage grow on bones and why: at the ends so the bones will elongate
which phase of muscle twitch is a stimulus applied?: in lag phase
__marrow cavity formed by osteoclasts and trabelculae form spongy bone: ossification center in endochondral bone formation
__penetrated by blood vessel, osteoblasts and osteoclasts: diaphysis -endochondral bone formation
___act to move the levers at 2 points. R and E or W: resistance :force to be overcome and effort or wor: force require to overcome resistance; supplied by skeletal muscles
___destroys bone & enzymes digest protein, acid dissolves minerals and is involved in remodeling: osteoclasts part of bone cells
_____mature bone cells: Osteoclasts "trapped" ostoblasts from bone cell
_____secrete to form bone: osteoblasts from bone cells
