Question

Draw the shapes of the different cells in the human body and Explain it.

Answer 1

Answer:

1. smooth muscle cell
2. blood cells
3. nerve cells
4. Bone cells
5. fat cells
6. sperm
7. ovum

Explanation:

• smooth muscle cell -Smooth muscle cells are spindle-shaped and have single elongated nuclei. ... Smooth muscle cells contain thin (actin) and thick (myosin) contractile filaments as well as cytoskeletal filaments. The thin filaments are the most conspicuous feature of smooth muscle cells.
• blood cells-A blood cell, also called a hematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
• nerve cells-The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).
• bone cells -Bone cells are the cells that make up bone tissue. Bone is a highly specialized connective tissue with three main functions; to protect the internal organs, to create a rigid frame for muscular movement, and to store minerals such as calcium and phosphorous.
• fat cells-Adipose cell, also called adipocyte or fat cell, connective-tissue cell specialized to synthesize and contain large globules of fat. ... The fat stored in these cells in part comes directly from the fats eaten and in part is manufactured within the body from fats and carbohydrates in the food and sometimes from protein.
• sperm-Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction. Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia.
• ovum-Ovum, plural ova, in human physiology, single cell released from either of the female reproductive organs, the ovaries, which is capable of developing into a new organism when fertilized (united) with a sperm cell. ... Within the follicle the ovum gradually matures (see oogenesis).
