Study Notes
Connective Tissue Types
- Dense regular connective tissue features tightly packed, parallel collagen fibers, primarily found in tendons and ligaments.
- Dense irregular connective tissue is mainly found in the dermis of the skin and around joints, providing strength in multiple directions.
- Interwoven collagen fibers characterize dense irregular connective tissue, forming capsules around organs such as the liver and kidneys.
Blood and Formed Elements
- Not all components of blood are considered formed elements; for instance, plasma is not a formed element.
- Formed elements include red blood cells, white blood cells, and platelets.
Tissue Functions
- Connective tissue supports soft tissues and body weight, providing shock absorption.
- The primary function of dense regular connective tissue is to provide tensile strength and resistance to pulling forces.
- The main function of epithelial tissue is to cover body surfaces, form barriers, and facilitate absorption and secretion.
- Bone or osseous tissue serves to support, protect organs, and store calcium.
Muscle and Membranes
- Skeletal muscle tissue is responsible for movement of large body muscles.
- The serous membrane covering abdominal organs is the peritoneum.
- Synovial membranes in joint cavities facilitate lubrication and reduce friction during movement.
- Mucous membranes line passageways in the digestive, respiratory, urinary, and reproductive tracts, providing protection and secretion.
Cartilage Types
- Hyaline cartilage is commonly found in the ribs, nose, and trachea.
- Fibrocartilage provides strength and absorbs shock, found in intervertebral discs and knee joints.
- Elastic cartilage is located in structures requiring flexibility, such as the ear.
Tissue Interaction and Healing
- Epithelial and connective tissues collaborate to form tissue membranes, creating protective layers throughout the body.
- Mast cell activation in response to injury can trigger inflammation, with symptoms including swelling, redness, heat, and pain.
- Chemicals released during mast cell activation include histamines and prostaglandins, stimulating inflammation.
Aging and Tissue Regeneration
- Aging can lead to decreased elasticity and resilience in various tissues, impacting their function.
- New cells regenerate in injured areas through processes like mitosis and stem cell activation, promoting tissue healing and repair.
Inflammatory Response
- Signs and symptoms of the inflammatory response include swelling, redness, elevated temperature, and pain.
- An infection caused by pathogens can lead to inflammation, indicating the body's defensive response.
