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.
