Lecture 3: Connective Tissue

These flashcards cover key terminology and concepts related to connective tissue as discussed in lecture three.

Connective Tissue

The most abundant and widely distributed primary tissue in the body, responsible for supporting various structures.

Extracellular Matrix

The non-cellular component present within all connective tissues, consisting of ground substance and connective tissue fibers.

Fibroblasts

A common cell type found in connective tissue that secretes connective tissue fibers and ground substance.

Adipocytes

Fat cells that store energy and provide cushioning and insulation.

Mast Cells

Cells involved in immune responses, known for releasing histamine and mediating inflammation.

Macrophages

Immune cells that perform phagocytosis, destroying foreign particles and damaged cells.

Collagen Fibers

Strong and abundant fibers in connective tissue that provide rigidity and strength.

Elastic Fibers

Fibers that allow stretch and recoil, found in structures like the aorta and vocal cords.

Reticular Fibers

Thin, branched fibers that form a supporting network in various organs, such as lymph nodes.

Loose Connective Tissue

A type of connective tissue characterized by a spacious structure with fewer fibers and cells.

Dense Connective Tissue

A type of connective tissue with densely packed fibers, providing strong support and resistance to stretching.

Cartilage

A flexible connective tissue that provides support and protection but lacks blood supply for self-repair.

Bone

A rigid connective tissue that supports and protects the body, composed of cells, a bony matrix, and blood supply.

Blood

A fluid connective tissue that transports nutrients, gases, and wastes throughout the body.

Hyaline Cartilage

The most abundant type of cartilage found in the rib cage and joints, providing flexible support.

Fibrocartilage

A type of cartilage that withstands pressure and provides support, found in intervertebral discs.

Elastic Cartilage

A type of cartilage that maintains shape while allowing flexibility, found in the ear and epiglottis.
