Study Notes
Body Tissues
- There are four kinds of body tissues: epithelial, connective, muscle, and nervous tissue.
Structural Organization of the Human Body
- The human body has four levels of structural organization: cells, tissues, organs, and organ systems.
Tissue Function
- A tissue is a group of similar cells that perform a specific function.
- Tissues function together to form organs, and organs work together to form organ systems.
Body Cavities
- There are four major body cavities in the human body: cranial, thoracic, abdominal, and pelvic cavities.
Stem Cells
- Embryonic stem cells are derived from embryos and have the ability to differentiate into all types of cells in the body.
- Adult stem cells are found in adult tissues and have a limited ability to differentiate into different cell types.
Epithelial Tissue
- Epithelial tissue lines most body surfaces and protects other tissues from damage and dehydration.
- It also forms glands, such as sweat glands and salivary glands.
Muscle Tissue
- Muscle tissue is responsible for movement, contraction, and relaxation in the human body.
- There are three types of muscle tissue: skeletal, smooth, and cardiac.
Connective Tissue
- Connective tissue provides support, structure, and connectivity to the body.
- It is made up of cells and a matrix, and is responsible for holding organs and tissues together.
Nervous Tissue
- Nervous tissue is responsible for transmitting and processing information in the human body.
- It is found in the brain, spinal cord, and nerves, and is composed of neurons and glial cells.
