nuclei very many, close to the membrane 1-2 located centrally only 1 in the centre of the cell
nuclear diameter and form 8-10 µm, lens-like ~ 12 µm, ovoid 10-25 µm, rod-like, corkscrew-like when contracted
order of filaments exactly parallel (striation) exactly parallel (striation) net-like (no striation)
Cohnheim fields yes yes no
cell form and length cylindric, up to 15 cm Y-like branched, 50-120 µm spindle-like, 50-200 µm, in uterus maximal 700 µm
tubulur system Triads: L-T-L tubules Dyads: L-T oder T-L tubules, rarely triads none
sarkoplasmatic reticulum
= L-tubules
very many many not present but Caveolae
mitochondria small, electron-dense, many very large, electron-dense, very many small, less electron-dense, rare, only close to nuclei
power very strong moderate small, shorten about 20 % of total length
duration only some minutes of full power never ending change of contraction & release contraction for hours possible
innervation mind controlled  autonomous  autonomous, low frequency of own activity
stimulation controlled by motor neurons influenced by vegetative nerves (& hormones) influenced by vegetative nerves & hormones
motor end plates present none, stimuli conducted by gap-junctions none, stimuli conducted by gap-junctions
regeneration possible none! easy by mitosis
specialities: Type 1 fibres = red fibres
higher endurance, much myoglobin, thinner
Type 2 fibres = white fibres
faster, less myoglobin, thicker
striated discs caveolae, Areae densae, Corpusculae densae
synthesis of prostacycline and elastic fibres
