Study Notes
Connective Tissue
- Connective tissue has relatively few cells integrated within an extensive extracellular matrix.
- Loose connective tissue serves as packing material with a loose weave of fibers.
- Cartilage is located at the ends of long bones, such as the femur.
- Blood is the connective tissue specialized for transport, containing cells separated by an extracellular matrix.
- Examples of connective tissue include blood and cartilage, characterized by collagenous fibers.
Epithelial Tissue
- Stratified epithelium covers surfaces subject to physical forces, providing protection.
- Simple columnar epithelium, found in the intestines, is specialized for nutrient absorption.
- Simple squamous epithelium, located in the lungs, allows for efficient gas exchange by diffusion.
- Simple cuboidal cells line kidney tubules, facilitating filtration and secretion.
- Stratified cuboidal epithelium consists of multiple layers of box-like cells.
Muscle Tissue
- Smooth muscle is responsible for involuntary contractions in the digestive tract and arteries.
- Cardiac muscle consists of branched fibers, distinct from other muscle types.
- Skeletal muscle is attached to bones and is both striated and under voluntary control.
- All muscle types involve interactions between actin and myosin filaments.
- Smooth muscle surrounds internal organs, excluding the heart.
Nervous Tissue
- Neurons are specialized cells that transmit electrical impulses; their structure includes a cell body housing the nucleus.
- Glial cells provide nourishment, insulation, and support to neurons, facilitating overall nervous system function.
General Tissue Functions and Relationships
- Four primary tissue categories: nervous, epithelial, connective, and muscle.
- As animal body size increases, the surface-to-volume ratio decreases, affecting physiological processes.
- Epithelial tissue lines most exchange surfaces in multicellular organisms.
- Interstitial fluid mediates exchanges between body cells and the circulatory system in vertebrates.
- Muscle contractions drive the movement of food through the digestive tract.
