Document Summary
Evpp 110 lecture 21 what things make up the supporting ct matrix? proteoglycans made of chondroitin sulfate and proteins supporting ct cartilage cell type. Secrete anti-angiogenesis factor anti-angiogenesis factor anti-blood vessel growth cartilage is surrounded by perichondrium cartilage growth generally doesn"t grow unless it is damaged interstitial growth chondrocytes divide appositional growth cellular layer of perichondrium divides to become new chondrocytes. 3 types of muscle tissue skeletal, cardiac, smooth. Striated skeletal muscle function voluntary contraction myosatellite cells stem cells of skeletal muscle tissue striated marked with parallel bands of actin and myosin fibers. Limited repair ability intercalated disc connections between cardiocytes (desmosomes, proteoglycans, gap junctions)) cardiac muscle function involuntary- pacemaker cells help to establish regular rate of contraction. Cardiac muscle location heart cardiocytes cardiac muscle cells how many nuclei does cardiac muscle tissue have. Smooth muscle tissue locations walls of blood vessels and hollow organs, bladder, layers around respiratory, cardiovascular, digestive and reproductive tracts.
