Answer 1

The correct answer is option (c) smooth muscle.

There are mainly three types of muscles in human body.

1.Smooth muscle

2. Skeletal muscle

3. Cardiac muscle

*Smooth muscles are involuntary muscles. They are present in the walls of hollow organs except heart. Examples-intestine,stomach, uterus, urinary bladder. They are non striated muscles

*Skeletal muscle are striated muscles which are under voluntary control. These muscles are attached to bones by tendons. They provide support and movement of the skeleton.

*Cardiac muscle is an involuntary striated muscle found only in the heart. It helps to pump the blood.

*Dense connective tissue is a type of connective tissue which contains type 1 collagen fibres as the main constituents. It is classified into dense regular and dense irregular connective tissue. Ligaments and tendons are made of dense regular connective tissue. Dense irregular connective tissue is found in the lower layers of skin and sclera of eyeball.
