ANIMAL TISSUES

Submitted By: Jasveer Rana

Animal Tissues

•ANIMAL tissues are of four types:

•1.Epithelial.•2.Muscular.•3.Connective.•4.Nervous.

Epithelial Tissues

• This tissue forms outer living of the body. It protects interval organ from external enviroment.

• It is of four types:• Squamous.• Cubic.• Ciliated columnar.• Glandular.

Squamous Epithelium

• It is made up of thin, flat irregular shaped cells .

• It also forms a selectively permeable surface through which filtration occurs .

Cubic Epithelium

• It consists of cube like cell which are square in section but the free surface appear hexagonal.

• It is found in kindly tubules, thyroid, vesicles and in glands.

Ciliated Columnar

• This epithelial is formed by in the sperm ducts.

• The rhythmic, concenterated beating of the cilia moves solid particles in one direction through the ducts.

Muscular tissues

• This tissue is that which is responsible in our body.

• This tissue is divided in three types:

• Striated muscle.• Smooth muscle.• Cardiac muscle.

Striated Muscle

• The cells of this muscle have many nucleus.

• These muscle show alternate light &dark bands.

• These help in body movement.• These are present in our limbs.

Smooth muscle

• These have long cells which have single nucleus.

• The cells of this muscle is spindle in shape.

• They are also called unstraited because we can not control them

Cardiac muscle

• It is the muscle which is present in heart.

• These muscle are also called involuntary muscle.

• These muscle have cylindrical &branched muscle.

Connective tissues

• It serves as storage Sid of calcium & phosphate.

• Bone provides shape & skeleton support to the body.

• Cartilage provides support & flexibility.

Nervous tissue

• A Tissue which is specialized to transmit messages in our body is nervous transmit. Brain, spinal cord and nerves are all composed of nervous tissues.Nervous tissues contains highly specialized unit cells called nerve cells or neurons.
