TYPE OF CELL MAKE UP EACH TUSSUE
Epithelial tissue - composed of epithelial cells, which are closely packed and form a protective barrier or lining on body surfaces or cavities.
Connective tissue - composed of different types of cells, including fibroblasts, adipocytes, macrophages, and mast cells, and provides support and structure to organs and tissues.
Muscle tissue - composed of muscle cells or myocytes, which can contract and produce movement.
Nervous tissue - composed of neurons and glial cells, which transmit and process information through electrical and chemical signals.
In multicellular organisms, various types of cells come together to form different types of tissues. Here are some of the main types of tissues and the cells that make them up:
1. Epithelial Tissue:
- Epithelial cells make up this tissue.
- Different types of epithelial cells such as squamous, cuboidal, and columnar form different types of epithelial tissues found in the skin, lining of organs, and glands.
2. Connective Tissue:
- Connective tissue is composed of various cells, including:
- Fibroblasts: Responsible for producing and maintaining the extracellular matrix.
- Adipocytes: Store fat.
- Mast cells: Involved in the inflammatory response.
- Macrophages: Engulf cellular debris and pathogens.
- Chondrocytes: Found in cartilage.
- Osteocytes: Found in bone tissue.
3. Muscle Tissue:
- Skeletal Muscle Cells: Form skeletal muscles and are responsible for voluntary movements.
- Smooth Muscle Cells: Found in the walls of hollow organs and blood vessels, responsible for involuntary movements.
- Cardiac Muscle Cells: Form the walls of the heart, responsible for rhythmic contractions.
4. Nervous Tissue:
- Neurons: Specialized cells that transmit electrical signals.
- Glial Cells: Serve supportive functions for neurons, such as providing structural support, insulation, and nutrient supply.
It's important to note that different tissues may contain different cell types, and the specific composition may vary depending on the organ or body system.
