Types of Muscle Tissue and Function
Muscular tissue is composed
of muscle cells, it is specialized cells that have the ability to contract and expand
and have tensile strength. It produces
the forces responsible for movement of the body parts such as arm, legs,
heart, stomach and other parts of body.
Know here embryonic
origin of muscle tissue.
Muscle tissue involves in-
1. Help in contraction and relaxation
2. Responsible for movement, locomotion
3. Support to bone
4. Heat store, produce heat
5. Provide protection
Check out here types of
epithelial tissue and types of
connective tissue.
Classification of Muscle Tissue
Classifications are-
A. According to Structure
1. Striated Muscle Tissue
1. Microscopic band seen in muscle tissue
2. Help in contraction and relaxation
2. Non Striated Muscle Tissue
1. No bands or striation are seen
2. Not help in contraction and relaxation
For example, nose and earlobe
B. According to Function
1. Voluntary Muscle Tissue
Voluntary muscle tissue contract and relax under
conscious control.
For example; biceps, triceps, quadriceps.
2. Involuntary Muscle Tissue
Involuntary muscle tissues are not under conscious control.
For example; smooth and cardiac muscle, heart pumping, blood
vessel.
For example; eat voluntary after that metabolism isn’t in voluntary
control.
C. According to Location
1. Skeletal Muscle Tissue
Tendons attach
skeletal muscle tissue to bones throughout body.
2. Visceral Muscle Tissue
Visceral muscle tissue present in viscera (internal organs),
inner covering, hollow organ. For example; stomach, intestine.
Visceral muscle tissue sometimes known as smooth muscle.
3. Cardiac Muscle Tissue
Present in the heart.
Cardiac muscle tissue or myocardium is
specialized type of muscle tissue that forms the heart.
Types of Muscle Tissue
1. Skeletal Muscle tissue
Muscle tissue is striated muscle or striped muscle; contain
alternating light and dark bands, it is visible.
Voluntary muscles
are voluntary muscle (under voluntary
control) and made to be contract; make it move (location).
Skeletal muscles are attached to bones (skeletal) by tendons.
Function
1. Movement of bones
2. Eye movement
3. First part of swallowing
Location
1. Muscle that attach to bone
2. Extrinsic eyeball muscle
3. Upper third of the oesophagus
2. Smooth Muscle Tissue
Smooth muscle is involuntary muscle. It is smooth and non-striated; not band present.
Function
1. Movement of substances along duct
2. Movement of substances along respective tracts
3. Changing diameter of blood vessels, regulation of blood
pressure
5. Changing diameter of pupil and shape of lenses
Location
1. In the duct of gland
2. In the wall of blood vessels and large lymphatic vessels
3. In wall of respiratory and genitourinary tracts
4. Intrinsic eye muscle, iris and ciliary body
5. Digestive stomach, intestine, gall bladder except the
heart
3. Cardiac Muscle Tissue
Cardiac muscle tissue found only in heart. It forms the
myocardium (middle layer of heart) responsible for contraction.
Cardiac muscle is striated like skeletal muscle. It is involuntary striated muscle tissue found
only in the heart, responsible for contraction and allows the t to pump
blood.
Cardiac muscle tissue is under involuntary control like
smooth muscle.
Cardiac muscle tissue is controlled by ANS (autonomic
nervous system).
Location
Wall of the heart
Function
Contraction of heart

tissue and what are types of nervous tissue?
Function of Muscular Tissue
The important function of muscular tissue are-
1. Ability to contract
2. Generate heat
3. Muscle movement
4. Provide support
5. Help in contraction and relaxation
6. Provide protection
7. Provide stability and durability
8. Maintenance of posture
9. Helps in respiration
10. Generate force
11. Elastic ability
12. Communication verbal and facial
13. Joint stabilization
14. Blood circulation
