Tissues
Definition: a group of closely associated cells
that perform related functions and are similar
in structure.

3. Maninder Kaur M.Pharm(Pharmacology)
Types of Tissue
1)Epithelium - Covering
2)Connective - Support
3)Muscle - Movement
4)Nervous - Control

4. Epithelial Tissue
• Epithelium: It is a sheet of cells that covers
a body surface or lines a body cavity; also
form most of the body’s glands
• Roles: as interfaces and as boundaries
• Functions:
• Protection.
• Sensory reception.
• Secretion.
• Absorption.
• Ion transport.
• Filtration .
• Formation of slippery surfaces for movement
Maninder Kaur M.Pharm(Pharmacology)

5. Special characteristics of
epithelium tissue
• Cellularity
• Specialized contacts
• Polarity
– Free upper surface
– Lower surface contributing basal lamina to
basement membrane
• Support by connective tissue
• Avascular but innervated
– Without vessels
– With nerve endings
• Regeneration

6. Maninder Kaur M.Pharm(Pharmacology)
• Simple: just one
layer or cell
shape
• Stratified:
multiple layers
and cell shapes
Classes of Epithelium tissue

7. Maninder Kaur M.Pharm(Pharmacology)
Simple Epithelium Tissue
Type Cell shape Example
Squamous Squashed Endothelium (lines blood
vessels), mesothelium
(serous lining of celom).
Cuboidal Cubed Walls of glands.
Columnar
Ciliated
Glandular
Columns
Cilia Present
Multi cellular
Lining of gut tube;
sometimes with cilia like
lining of uterine tube.
Pseudo-stratified Flat cells give rise
to columns
With cilia in respiratory
tubes to move
mucous/particles out of
lungs.

10. Simple columnar epithelium tissue

11. Maninder Kaur M.Pharm(Pharmacology)
Stratified Epithelium Tissue
• Squamous
– E.g. epidermis
• Transitional
epithelium
– E.g. urinary
structures--bladder
– Stretches from 6
cells to 3 cells thick
as bladder fills and
expands.

Cell Junctions b/w cells
1. Desmosome: binding spots between
cells with proteins called cadherins.
2. Tight junctions: impermeable
3. Gap junctions: tubes that let small
molecules pass between cells

CONNECTIVE TISSUES
• It is originated from embryonic tissue called
mesenchyme.
• Most diverse and abundant type of tissue.
• Function: To protect, support and bind together
other tissues
– Bones, ligaments, tendons, Areolar cushions.
– Blood cells replenished.
• Cells separated from one another by large amount
of nonliving extracellular matrix

33. Muscular Tissue
• Tissue with cells having fibers specialized for
contraction.
 Skeletal MuscleSkeletal Muscle (Striated, voluntary)
•Parallel elongated cells (fibers)
• multinucleated and each cell is the length of the muscle.
•Light meat, Dark meat—Slow twitch, fast twitch muscle
Smooth MuscleSmooth Muscle (Visceral, involuntary)
•Cells are long and tapered.
•Organized into sheets of muscle.
Cardiac MuscleCardiac Muscle
•Intercalated disc
•Myogenic
•branched

37. Nervous tissue
• Cells specialized to polarize and
depolarize.
• Cell is a neuron
• It consist of mainly- Axon, Cyton,
dendrites.
