Question

describe the three types of muscle tissue?

Answer 1

ANSWER -

There are 3 type of muscle tissues they are :

1. SKELETAL MUSCLE

• This muscle helps to move bona ans other structures.
• Found in stratified form.
• This involves voluntary control which comes under Somatic nervous system.
• Skeletal muscles are attached to bones through bundles of collagen fibers - Tendons.
• Skeletal muscle maintain posture,control internal movements,stabilise bones and joints and generate heat.
• Example of skeletal muscle : biceps branchi, triceps branchii, branchialis anticus etc.

2. CARDIAC MUSCLE

• This is a specialised form of muscle tissue.
• Helps to pump blood throughout the body.
• Cardiac muscle is only found in heart, which makes up the mass of heart.
• Cardiac muscle are involuntary and intrinsically controlled.
• They are striated,branched and single nucleated.
• Presence of Myofibrils and mitochondria provide strength and endurance to pump blood entire life time.
• Pacemaker cells controls the contractions of heart.

3. SMOOTH MUSCLE

• This is a involuntary muscle.
• This muscle consist of narrow spindle shaped cells with a single centrally located nucleus.
• These line inside og hollow organs such as arteries, lungs, bladder, digestive system and reproductive system.
• Smooth muscle have more ability to contract than skeletal muscle.
• They can maintain longer contractions.
• Smooth muscle helps to push out baby from the uterus, helps to pump blood, helps to push out urine,move food through digestive tract.
