Study Notes
White Blood Cells
- Microscopic slides display various types of white blood cells, essential components of the immune system.
- Function in identifying and combating infections, foreign substances, and diseases.
Platelets
- Microscopic slides include red blood cells alongside platelets, identifiable through labeled arrows.
- Platelets play a crucial role in blood clotting and wound healing by aggregating at sites of injury.
Pseudostratified Epithelium
- Composed of a single layer of cells that appear stratified due to differing cell heights.
- Often found lining respiratory passages, aiding in mucus secretion and movement of respiratory particles.
Simple Columnar Epithelium
- Features a single layer of tall, columnar cells that may have microvilli or cilia.
- Primarily functions in absorption and secretion, commonly located in the digestive tract.
Simple Cuboidal Epithelium
- Made up of a single layer of cube-shaped cells.
- Frequently found in glands and ducts, involved in secretion and absorption processes.
Skeletal Muscle
- Composed of long, cylindrical fibers with striations and multiple nuclei, responsible for voluntary movement.
- Attached to bones, enabling movement and posture control through conscious effort.
Cardiac Muscle
- Involuntary muscle tissue with striated fibers, interconnected by intercalated discs.
- Found exclusively in the heart, it facilitates rhythmic contractions to pump blood.
Smooth Muscle
- Consists of spindle-shaped, non-striated cells, contributing to involuntary movements.
- Located in walls of hollow organs like the intestines and blood vessels, regulating functions such as digestion and circulation.
Nerve Cell
- Specialized cells responsible for transmitting nerve impulses throughout the body.
- Composed of a cell body, dendrites, and an axon, enabling communication between different body parts.
Red Blood Cells
- Biconcave, disc-shaped cells responsible for transporting oxygen from the lungs to body tissues.
- Contains hemoglobin, which binds to oxygen and facilitates carbon dioxide removal from tissues.
