(38 cards)
straited, unbranched and multinucleated
skeletal muscle cells
where do peripheral nuclei appear on skeletal muscle
transverse section ed nuclei
what is epimysium
connectuve tissue that suurounds muscle
what is is perimysium
surrounds single fascicle
what is endomysium
connective tissue around single fibre
what does muscle contain
fasiciles, myofibril, sarcomeres
type 1 muscle
dark meat (duck)
type 2 muscle
white meat (chicken)
what is semi rigid and deformable, permeable, avascular and contains chondrocytes
cartilage
what is the most common type of cartilage
hyaline
where is hyaline cartilage found
at articular surfaces, tracheal rings, costal cartilage, growth plates and is a precursor in fetus to many bones
where do chondrocytes sit
in small spaces called lacuna
what is rigid, non permuable, and has cells that need to be nourished by blood vessels
bone
what are the roles of bone
provudes support, levers for movement, protection of internal organs, calcium store, haemopoesis,
what is haemopoesis
blood cell production within bone marrow
what is bone comprised of
bioapatite, collagen, water, non collagen proteins
what are margins of osteon
cement lines
what makes up the shaft of bone
outer shell of dense cortical bone
what occupies the end of bone
cancellous or trabecular bone
what is haversian canal
where osteoclasts drill into the bone with vessel growing in there
where are nuclei in skeletal muscle
at the periphery of the fibre just under the cell membrane
what is a bundle of muscle fibres called
fascicles
type 1 muscle fibres also called
red fibres
what type of muscle fibre is rare
type IIA
