Study Notes
- The text discusses different levels of organization in the body, starting from cells, tissues, organs, organ systems, and the organism as a whole.
- Cells are the basic unit of life, and they come together to form tissues.
- Two or more tissue types make up an organ, such as a blood vessel.
- Organs work together to form organ systems, like the cardiovascular system.
- The human body consists of multiple organ systems, including the muscular, reproductive, lymphatic, respiratory, and digestive systems.
- Nervous tissue is associated with the nervous system and is composed of neurons and neuroglia.
- Neurons are excitable cells that transmit electrical signals for communication and control in the body. They typically have many branches.
- Neuroglia are supportive cells that do not transmit electrical signals. They come in various types and outnumber neurons in the body.
- Muscle tissue is involved in movement and comes in three types: skeletal, cardiac, and smooth muscle.
- Skeletal muscle contracts and pulls on bones to produce movement.
- Cardiac muscle contracts to pump blood in the heart.
- Smooth muscle is found in various organs and can contract to produce movement or perform secondary functions like thermal regulation.
- Muscle tissue has four key properties: extensibility, elasticity, contractility, and excitability.
- Extensibility refers to the ability to stretch and return to original size.
- Elasticity refers to the ability to stretch and recoil.
- Contractility refers to the ability to shorten.
- Excitability refers to the ability to respond to electrical signals.
- Epithelial tissue is not discussed in the text, but it is a type of tissue that covers the body's external and internal surfaces and lines the various body cavities. It plays a role in protection, secretion, absorption, and sensory perception.
Test your knowledge of the functions and structure of epithelial tissues. Explore how epithelial tissues cover and line various surfaces in the body, including the skin and hollow organs.
