Question 6

Skeletal Muscles:

Answer 6

Tendious attachments to bone or soft tissue and cross 1 joint

Voluntary movements by pulling on a bone to initiate action at a joint

Has STRIATIONS and several nuclei in each cell

Question 7

Cardiac Muscle:

Answer 7

Located ONLY in the wall of the hear wall

Involuntary contractions of the heart chambers(heart beat)

Less organized strations
Cnetrally located nuclei
Cells only have 1 nucleus

Question 8

Answer 8

Located in the walls of internal organs
Involunatry movement of functions of organs
