This presentation contains the different forms of cells according to shape.

1. Forms of cells
By: Mr. Nikko Lorenz Lawsin
According to shape

2. NOTE:
Our body system contains different types of cells
that perform specific functions. As we observed,
cells vary in terms of shapes, the differentiation
in shapes of the cell is accompanied by its
specific functions.

3. 1.Sphericalthey are specialized for transport
Red Blood Cells Human Egg Cell

4. 2.OvalHuman sperm cells (Oval & flagellated to propel the movement
of the sperm along reproductive tract of the female).
Human Sperm Cells Frog Erythrocytes

5. 3.Cuboidalthey cannot be seen as individual cells rather they are group of
cells. It is commonly seen in kidney tubules and salivary glands.
Kidney tubules Salivary Glands

6. 4.Squamous thin and square-like. It can be found in outermost layer of the skin.
Skin Epidermis

7. 5.Columnarthe length is greater than the width.
In intestine, it increases the surface area of absorption with
the structure known as villi.
Small Intestine

8. 6.Ciliated Columnarlocated along respiratory tract for transport and
filtration of air
Bronchus

9. 7.PolygonalMany-sided cells.
Adipocytes
These cells give rise to adipose tissues that can be found
in many body structures such as mammary glands

10. 8.Cylindricalpossessed by skeletal and cardiac muscle cells,
designed for contraction.
Skeletal Muscle
 Intercalated disks, allows simultaneous movement of cardiac muscles.
Cardiac muscles

11. 9.Fusiformthese sets of cells are rounded at the center but
tapering at the end
Smooth Muscles
 These muscles are only found in Internal Organs such as Digestive Tract

12. 10.Stellate or Star-shapeddesign for transmissions of impulses
Neurons or nerve cells, this is designed to transmit
signals through axons and dendrites
Neuron

13. 11.Amorphousthey do not have definite shapes or it is changing to perform
amoeboid movement. This is designed for phagocytotic
activities such as engulfing of foods.
Lymphocytes

14. 12. Spider-shaped/web-shaped cells
Channel of bone canals
Bone Cells
