15 Animal Tissue
· Body Organization : Body organisation process remains dynamic where multicellularity resulted
with complexity. Group of cells structurally and functionally became similar and organised tissue.
Cells ® Tissues ® Organs ® Organ systems ® Complex body.
· There are four basic tissue types :
(1) Epithelial tissue (2) Connective tissue
(3) Muscular tissue (4) Nervous tissue
Epithelial tissue Ñ
Definition : A tissue which covers external surface of the body and interal free surface of many
organs.
Features :
· It forms external surface and internal surface or many organ and body.
· The cells are arranged very close to each other with very little extracellular material or matrix which
is a product of these epithelial cells.
· The cells are thin, polygonal, cuboidal or columnar. They rest on a non-cellular basement
membrane.
Location :
· The lining of the skin, alimentary canal, blood vessels, digestiveglands, respiratory organs, etc.
Function :
· It is highly specialised for protection, absorption and secretion.
· The skin and most of the organs are covered by a epithelial membrane for protection.
· Some of the epithelial surfaces are absorptive and secretory.
Group :
· Based on structure and function epithelial tissues are divided into two main groups :
(1) Covering epithelial (2) Glandular epithelial

· Squamous epithelial tissue :

Location :The outer most layer of skin of frog, inner lining of lung alveoli, lining of blood vessels,
Bowman's capsules of kidney, peritoneum of body cavity.

· Function : Protection of underlying tissue.
Features :
· Cells are joined by cement material.
· In surface view, this tissue seems to be composed of flat tiles like that of a pavement.
· Cuboidal epithelial tissue :
Location : Proximal tubules of kidney, salivary glands, pancreatic ducts, thyroid gland and ovary.
Function : In addition to protection, these cells are participate in secretion (gastric juice, hormone,
etc.), excretion and absorption.
Features :
· Cells are square in vertical sections, polygonal in horizontal section.
· Cells of absorptive surfaces often bear microvilli on their free ends.
· Columnar epithelial tissue :
Location : It forms the lining of the mucous membrane of the stomach, gall bladder, urinogenital
organs and their ducts.
Function : Secretion and absorption. Reabsorption and secretion in uriniferous tubules and absorption
of digested food in alimentary canal.
Features :
· Cells of this type of epithelia are elongated and are placed side by side like tall pillars.
· Their inner ends are generally narrow but free ends are broad having polygonal surface.
· Ciliated epithelial tissue :
Location : Auditory canal, uterine tube, respiratory tract.
Function : Cilia moves particle, free cells or mucus in a specific direction.
Feature : It is merely a modification of columnar epithelium.
· Cilia are developed from basal granules of cytoplasm.
· Cells bear thin protoplasmic processes on their surfaces called cilia and hence this tissue is called
ciliated epithelium.
· Pseudo - stratified epithelium tissue :
Location : Inner lining of trachea, large bronchi.
Function : Removes mucus and secretions.
Features : It is the simple columnar epithelium.
· The regular arrangement of the cells is distorted.

tissue.
· It is made up of fibres and cells. Fibres are of two types :
· White fibers : It is wavy, unbranched and are arranged in bundles. It is made up of protein collagen.
It can bear weight, pressure or tension.
· Yellow fibers : It is straight, branched and are not arranged in bundle. It is made up of elastin and
is elastic. It forms delicate network. It cannot bear weight, pressure or tension.
· Cells are of three types, i.e. Fibroblasts; Macrophages and Mast cells.
· Mast cells secretes heparin, histamine and serotonin.
(2) Adipose tissue Ñ
Location : Occurs in abundance in the subcuteneous beneanth the skin, around kidney,
mesenteries, bone marrow.
Functions : As it is present as subcutenous tissue, it helps to conserve the body heat.

as follow.

265

Types :
(1) Hyaline cartilage Ñ
Location : It is present in larynx, trachea, sternum, hyoid and ribs, etc.
Structure : The word hyaline is derived from the correct word "hylos" which means "glass" and the
hyaline cartilage was so named because in the gross, it appears as a clear bluish coloured
glassy surface.

erythrocytes per cubic milliliter, while that of adult female contains 39,00,000 to 55,00,000 per cubic
milliliter.

Voluntary muscle Involuntary
the movement of whole body.
or
· It has three types. Smooth muscle

· Skeletal muscle or striated muscle :
· The muscle fibers are the thin units of skeletal muscle. Each muscle fibre is a single thin and
elongated cell provided with many nusclei.
· The muscle fibers are arranged in bundles (fasciculi).
· In higher animals, they are found associated with the skeleton.
· They are attached to bones by tendons.
· Muscle fibres can be contracted as desired. So, they are also known as voluntary muscles.
· Because of their appearance they are called striated or striped muscle.
· Structure of muscle fibers Ñ
· The cytoplasm (sarcoplasm) of each fiber contains large number of myofibrils.
· Each fiber has an extensive sheath, the sarcolemma.
272

· The muscle fibres show cross or transverse striations of alternative light and dark bands.
· The darker bands are called "A" band.
· The lighter bands are called "I" band.

· Nervous tissue :

Nervous tissue

Neurons Neuroglia
- Long processes - Short processes
- It conducts nerve impulse - It supports neurons
· Structure of Neurons :
· Typically each neuron consist of a cell body and branching fibres.
· Cell-body : It is called cyton, cytoplasm of cyton contains a large and spherical nucleus. There are
large number of dark particles called Nissl's granules.

Processes (or fibres)
(Fibres arises from periphery of cyton)

Axons Dendrites
- It is longer - It is shorter
- Conducts impulse away from neuron - Conducts impulse towards the neuron
- It is called efferent - It is called afferent

Types of Neurons

Unipolar Bipolar Multipolar
- Only one process - One axon and one - More than two processes
- e.g. In Embryo dendrite - e.g. Brain, Spinal Cord
- e.g. Retina
· The nerve fibres may be surrouned by two concentric sheaths. The inner is known as medulla or
myelin sheath.
· It is surrounded by a transparent cellular sheath, the neurilemma.
· The neurilemma sheath is made up of single layer of flat expanded Schwann's cells.
· Each myelinated nerve fiber shows constrictions at regular intervals called nodes of Ranvier.
· The nerve endings of axon are not in direct physical contact with nerve endings of dendrites of
another neuron. This physical gap is called synapse.
· Nerve impulses pass between neurons through the synapse with the help of a hormone Acetylecholine
called Neurotransmitters.
