Histology of Connective Tissue & Membranes

These flashcards cover key vocabulary related to the histology of connective tissues and membranes, including definitions and functions.

Connective Tissue

The most common type of primary tissue in the human body, composed of cells and an extracellular matrix.

Extracellular Matrix

A complex network of proteins and carbohydrates surrounding cells, consisting of ground substance and fibers.

Collagen Fibers

Strong, tough fibers that provide strength and are resistant to stretching; found in tendons and ligaments.

Elastin Fibers

Fibers that provide elasticity and strength, made of the protein elastin.

Reticular Fibers

Netlike fibers that provide structural support, typically found in the spleen and lymph nodes.

Fibroblast

A cell in connective tissue that produces collagen and other fibers.

Adipocyte

A cell specialized for storing fat.

Leukocyte

A white blood cell that is part of the immune system.

Areolar Tissue

A loose connective tissue that binds epithelium to underlying tissues and allows nutrient diffusion.

Adipose Tissue

A type of loose connective tissue that stores lipids for fuel and provides thermal insulation.

Fibrocartilage

A type of cartilage providing strong support and the ability to withstand heavy pressure, found in intervertebral discs.

Hyaline Cartilage

A supportive connective tissue with a rubbery matrix, found in the nose and connecting ribs to the sternum.

Elastic Cartilage

Cartilage that provides strength and exceptional stretchability, found in the external ear.

Compact Bone

The dense, hard exterior of bones that provides support and protection.

Spongy Bone

Bone with a porous structure located inside bones, supports and protects while providing storage.

Blood

A connective tissue that transports nutrients, gases, wastes, and aids in immune response.

Dermis

The inner layer of skin composed of collagen, elastic, and reticular fibers, containing dermal papillae.

Hypodermis

The subcutaneous tissue primarily made of adipose, serving as an energy reservoir and thermal insulator.

Burns

Injuries caused by heat, chemicals, or radiation, which can result in fluid loss and infection.
