3.10 Study Guide: Body Tissues, Membranes, and Integumentary System

Vocabulary flashcards reviewing key histology, body membrane types, and integumentary system structures from Study Guide 3.10.

Epithelial Tissue

An avascular tissue type that covers body surfaces and cavities.

Simple Epithelial Tissue

Epithelial tissue that consists of a single layer of cells.

Connective Tissue

Tissue whose primary function is protection, support, and binding of body parts, with some forms (such as cartilage) being avascular.

Skeletal Muscle

Muscle tissue that contracts voluntarily to move the body.

Cardiac Muscle

Involuntary muscle tissue found only in the heart.

Smooth Muscle

Involuntary, non-striated muscle tissue found in hollow organs.

Nervous Tissue

Tissue specialized to send electrical impulses throughout the body.

Cutaneous Membrane

A membrane that provides a barrier against environmental damage.

Serous Membrane

A membrane that covers internal organs and secretes lubricating fluid.

Serous Fluid

A lubricating secretion that prevents friction between moving internal organs.

Mucous Membrane

A membrane that lines open cavities of the body exposed to the exterior environment and is always kept moist.

Synovial Membrane

A membrane that secretes fluid to reduce friction in joints.

Keratinocytes

Skin structures that produce keratin to strengthen the outer layer of the skin.

Sebaceous Glands

Glands that secrete an oily substance called sebum rather than sweat.

Sebum

The oily secretion produced by sebaceous glands.

Cyanosis

A blue discoloration of the skin resulting from poor oxygenation.

Hair Follicle

An accessory skin organ whose primary function is to protect and cushion body parts.

Melanin

A pigment produced by the deepest layer of the epidermis that protects the skin from ultraviolet (UV) radiation.

Epidermis

The outermost layer of the skin, whose deepest cellular layer produces melanin.

Phagocytes

Cells located in the dermis that destroy bacteria and prevent infection.

Apocrine Glands

Glands situated in the armpits that activate during puberty.

Nail Bed

The structure from which nails grow, located beneath the nail plate rather than at the free edge.
