Which kind of muscle is involved in the following processes?
(a) Movement of the arm
(b) Contraction of blood vessels

(d) Movement of heart.
Answers
Answer:
Explanation:
a) Muscle involved in the movement of arm are The shoulder muscles include the deltoid and pectoralis major, which rotate the shoulder and move the arm toward and away from the centre of the body. The muscles of the upper arm include the biceps and triceps.
b) Vascular smooth muscle contracts or relaxes to change both the volume of blood vessels and the local blood pressure, a mechanism that is responsible for the redistribution of the blood within the body to areas where it is needed (i.e. areas with temporarily enhanced oxygen consumption).
c) smooth muscle
The walls of the alimentary canal include layers of smooth muscle controlled by the autonomic nervous system. Alternating contraction and relaxation of these muscles is called peristalsis. Peristaltic waves push the swallowed bolus down the oesophagus.
d) Cardiac branch
Cardiac muscle tissue is one of the three types of muscle tissue in your body. The other two types are skeletal muscle tissue and smooth muscle tissue. Cardiac muscle tissue is only found in your heart, where it performs coordinated contractions that allow your heart to pump blood through your circulatory system.
Answer:
1) Striated muscles
2)Unstriated muscles
3)Unstriated muscles
4)cardiac muscles
Explanation: because straited muscles are found in limbs,body wall,face and neck. And unstraited muscles are found in all tubular organs such as stomach, intestine, blood vessels, breathing passages and the organ concerned with urination and reproduction. Cardiac muscles are only found in wall of heart.
