| Question | Answer |
| 3 TYPE OF MUSCLE CELLS | SKELETAL, CARDIAC, SMOOTH MUSCLE |
| SKELETAL MUSCLE | ATTACH TO BONE
PROVIDE MOVEMENT & SUPPORT
PARALEL, CYLINDRICAL CELLS WITH STRIATIONS - UP TO 12" LONG (LARGEST) OF THE 3 |
| MULTINUCLEATE | SKELETAL MUSCLE CELL |
| SKELETAL MUSCLE UNDER WHICH CONTROL | VOLUNTARY - UNDER CONSCIOUS CONTROL
CONTRACTS RIPIDLY, TIRES EASILY - EXERTS VARYING AMOUNTS TO FORCE |
| CARDIAC | FORMS HEART WALL, CONTRACTIONS PUMP BLOOD
STRIATED, UNINUCLEATED |
| CARDIAC CONTAINS | INTERCALATED DISC - INTERCELLULAR CONNECTIONS BETWEEN CELLS
1) DESMOSOMES - PROVIDE STRENGTH
2) GAP JUNCTIONS - SPEADS CONTRACTION IMPULSE FROM CELL TO CELL |
| CARDIAC MUSCLE IS - VOLUNTARY OR INVOLUNTARY | INVOLUNTARY - CONTRACTS AT STEADY RATE; RESPONDS TO ANS, HORMONES |
| SMOOTH MUSCLE | FOUND IN VALLS OF HOLLOW ORGANS
USUALLY 2 LAYERS - LONGITUDINAL, CIRCULAR
* UNINUCLEATE, NON STRIATED |
| SMOOTH MUSCLE IS INVOLUNTARY OR VOLUNTARY | INVOLUNTARY - CONTRACTS SLOWLY,
GENERATES SUSTAINED CONTRACTIONS
RESPONDS TO ANS
HORMONES HELP BRAKE UP
MOVE FOOD, FLOODS THRU BODY - ELIMINATES WASTES |
