Lightly load movements to promote healing and strengthen tissue.

The first stage of wound healing lasting 1-5 days, characterized by inflammation.

The stage of wound healing from 5-21 days where tissue formation occurs.

Final phase of wound healing where tissue is restructured over time.

Collagen type III is replaced by stronger type I during remodeling.

A group of similar cells working together to perform a specific function.

There are four main types of tissues in the body: epithelial, nervous, muscular, and connective.

Covers body surfaces and lines cavities, protects against damage and dehydration.

Made up of nerve cells that transmit information throughout the body.

Enables movement of body parts through contraction.

Includes dense and loose connective tissue, bone, cartilage, and blood.

Examples include tendons, ligaments, and capsules; strong and supportive.

The stages through which the body repairs injuries: hemostasis, inflammation, proliferation, and remodeling.

Defense cells that clean damaged tissue and pathogens.

Higher permeability leading to pain, swelling, and loss of function.

Substances that cause vasodilation and increased permeability.

Cells that produce extracellular matrix (ECM) in connective tissue.

A network that provides structural support to cells in tissues.

Formation of new blood vessels during tissue healing.

The process by which the body repairs damaged tissue.

Includes heat, redness, swelling, pain, and loss of function.

The widening of blood vessels that occurs during inflammation, leading to heat and redness.

A type of collagen found in bone, tendons, ligaments, and skin; has high tensile strength.

A type of collagen primarily found in cartilage.

Molecules made of protein and sugar chains that bind water and stabilize collagen fibers.

Complex carbohydrates that are part of proteoglycans and help in water binding.

The resistance of a material to breaking under tension.

Structures formed by proteoglycans that bind with water and stabilize tissue.

A measure of a fluid's resistance to flow; higher with more GAGs.

Made up of cells and the extracellular matrix, including fibers and ground substance.

Major protein fibers in connective tissue that provide tensile strength.

Protein fibers allowing connective tissues to stretch and return to their original shape.

Thin fibers that form a supportive mesh in certain connective tissues, providing structure.

The non-cellular material in connective tissue that fills the space between cells and fibers.
