Anatomy & Physiology: The Tissue Level of Organization

Flashcards summarizing key vocabulary related to the study of tissues in anatomy and physiology.

Tissue

A group of cells in the body that work together for a common function.

Histology

The study of tissues.

Epithelial Tissue

Tissue that covers surfaces, lines passageways, and makes up certain glands.

Connective Tissue

Tissue that binds things together, provides protection, support, and integration of body parts.

Muscle Tissue

Tissue that responds to stimulus to contract and provide movement.

Nervous Tissue

Tissue that allows the propagation of electrochemical signals for communication throughout the body.

Glandular Epithelia

Modified epithelial cells primarily for synthesizing and secreting substances.

Endocrine Glands

Glands that release hormones into the bloodstream or interstitial fluid.

Exocrine Glands

Glands that release substances into a duct leading to the surface.

Connective Tissue Membranes

Membranes that include synovial membranes.

Epithelial Membranes

Membranes that include mucous membranes, serous membranes, and cutaneous membrane.

Mucous Membranes

Line passageways with external connections in digestive, respiratory, urinary and reproductive tracts.

Serous Membranes

Line cavities not open to the outside, typically double-walled.

Cutaneous Membrane

The skin, which is the exterior surface of the body.

Synovial Membranes

Line articulating joint cavities and produce synovial fluid.

Osteoblasts

Cells that build bone.

Osteocytes

Mature bone cells.

Osteoclasts

Cells that break down bone.

Action Potentials

Electrical signals that allow for the transmission of information in nervous tissues.

Neurons

Cells in nervous tissue that propagate information.

Neuroglia

Supportive cells in nervous tissue that assist neurons.

Astrocytes

Support cells that form a blood-brain barrier.

Collagen Fibers

Structural proteins that provide support to tissues.
