(Cell type) break down bone
osteoclast
(Cell type) is a mature bone cell that maintains bone matrix and act as stress or strain sensors
osteocyte
(Bone Cell Type) break down bone
osteoclast
(Bone Cell Type) is a mature bone cell that maintains bone matrix and act as stress or strain sensors
osteocyte
(Bone Cell Type) secretes unmineralized bone matrix called osteoid
osteoblast
(Bone Cell Type) is the immature cells that will become cartilage
chondrocyte
Connective tissue ensheathing a bundle of muscle cell
Perimysium
Bundle of muscle cell
Fascicle
Contractile unit of muscle
Sarcomere
(Bone structure) Layers of bony matrix around a central canal
concentric lamellae
(Bone structure) site of osteocytes
lacunae
(Bone structure) longitudinal canal carrying blood vessels, lymphatic, and nerves
central canal
(Bone structure) minute canals connecting osteocytes of an osteon
canaliculi
(Bone structure) inorganic slats deposited in organic ground substance
matrix
the structural units of spongy bone are called
trabeculae
What fibers does these describe?
1. Fatigue quickly
2. Is white in color
3. has a few mitochondria
Fast glycolytic fibers
what cell type maintains bone matrix and act as stress or strain sensor
osteocyte
(cell type) secretes unmineralized bone matrix called osteoid
osteoblast
(Cell type) immature cells that will become cartilage
chondrocyte
(Muscle Structure) connective tissue ensheathing a bundle of muscle cells
perimysium
(Muscle Structure) bundle of cells
fascicle
(Muscle Structure) contractile unit of muscle
sarcomere
(Muscle Structure) a muscle fiber
sarcolemma
(Muscle Structure) long filamentous organelle with a banded appearance found within muscle cells
myofibril
(Muscle Structure) actin/ myosin structure
myofilament
(Muscle Structure) cords of collagen fibers attached to muscle
tendon
imbalance that activates these bone cells would lead to a loss of bone density
osteoclasts
True or False osteoclasts are the bone cells that break down bone. If they were activated more than normal, you should expect to see bone loss
True
which ligament prevents the tibia from sliding forwards in the knee joint
anterior cruciate ligament
These are functions of the ……
1. Osteogenesis
2. Protects the bone
3. Provides anchoring points for tendons and ligaments
periosteum
(Muscle terms) Prime mover-responsible for producing specific movement
Agonist
(Muscle Structure) reverses particular movement
antagonist
(Muscle Structure) helps prime mover by reducing undesirable movement and adding extra force
synergist
(Muscle Structure) Gives a stable base
fixator
