Complete Study Guide: Tissues, Integument, and Homeostasis

This flashcard set covers key vocabulary and concepts related to tissues, the integumentary system, homeostasis, and related physiological processes.

Epithelial Tissue

Tightly packed cells that are avascular and regenerate quickly; functions include protection, secretion, absorption, and filtration.

Connective Tissue

The most abundant tissue type characterized by widely spaced cells and extracellular matrix that includes fibers and ground substance; functions in binding, support, transport, and protection.

Muscle Tissue

Tissue composed of elongated contractile fibers; includes skeletal (voluntary), cardiac (involuntary), and smooth (involuntary) types.

Nervous Tissue

Tissue consisting of neurons that send impulses, and glial cells that support them; functions in communication, integration, and control.

Apical Surface

The surface of epithelial tissue that is exposed to the lumen or outside environment.

Basal Surface

The surface of epithelial tissue that is attached to the basement membrane.

Collagen

The most abundant fiber in connective tissue, providing strength.

Elastin

A stretchy fiber in connective tissue that allows recoil.

Transitional Epithelium

A type of epithelium found in the urinary bladder that allows for stretching.

Homeostasis

The maintenance of stable internal conditions in the body despite external changes.

Negative Feedback

A control mechanism that counteracts changes to maintain a setpoint.

Positive Feedback

A process that amplifies a response until an endpoint is reached.

Granulation Tissue

Temporary connective tissue formed during the tissue repair process.

Hyperplasia

An increase in cell number.

Hypertrophy

An increase in cell size.

Atrophy

A decrease in cell size or number.

Neoplasia

Uncontrolled growth of cells, often resulting in a tumor.

Cutaneous Membrane

The skin; provides protection as a barrier to the external environment.
