There are differences between cells in function and structure. Each type of cell is specialized throughout the body to do different activities. There are five type of cells in our body:
1. NERVE CELL: The other name of nerve cell is NEURONS. They are electrically excitable cells in the nervous system that process and transmit information. Neurons are the core components of the brain, and spinal cord in vertebrates and ventral nerve cord in invertebrates, and peripheral nerves.
2. MUSCLE CELL: It is long and slender in shape, and contains fibers that help in relaxing and contracting action of the muscles. There are three types of muscles in our body: a) smooth muscleb) striated musclec) cardiac muscle.
3. EPITHELIAL CELL OR SKIN CELL: They are square in shape and flat. They give protection to the body. Skin is made up of two types of layers.a) dermis-outer layer of the body b) epidermis-inner layer of the body.
4. FAT CELL: These cells have large empty spaces for fat material storage. The another name is ADIPOCYTE. They are the cells that primarily composed of fat. They are specialized in storing energy as fat. There are two types of adipose tissue, white adipose tissue, and brown adipose tissue. They are also known as white fat and brown fat.
5. SEX CELL: They are of two types: a) SPERM (male sex cell) b) EGGS (female sex cell). Male sex cell is called GAMETE. Both male and female sex cells containing 23 single chromosome (all other body cells contain 23 sets of chromosomes). Female sex cell is called EGG.
