Fundamentals of Anatomy & Physiology - The Tissue Level of Organization

A comprehensive set of flashcards covering the key topics from the lecture on the tissue level of organization, including types of tissues, their characteristics, functions, and structural details.

What are the collections of specialized cells that perform specific functions called?

Tissues

What is the study of tissues known as?

Histology

List the four major types of tissues in the body.

Epithelial, Connective, Muscle, Nervous

What is the primary function of epithelial tissue?

Covers exposed surfaces, lines internal passageways, forms glands.

What function does connective tissue serve?

Fills internal spaces, supports other tissues, transports materials, stores energy.

What is specialized in muscle tissue?

Contraction.

What does nervous tissue do?

Carries electrical signals from one part of the body to another.

What are the characteristics of epithelial tissues?

Polarity, Cellularity, Attachment, Avascularity, Regeneration.

What are the functions of epithelial tissue?

Provide physical protection, control permeability, provide sensation, produce specialized secretions.

What are the types of cell junctions in epithelial tissue?

Gap junctions, Tight junctions, Desmosomes.

What do gap junctions do?

Allow rapid communication between cells.

How do tight junctions function in epithelial tissues?

Prevent passage of water and solutes between cells.

What is the difference between endocrine and exocrine glands?

Endocrine glands release hormones into the bloodstream; exocrine glands discharge secretions through ducts onto epithelial surfaces.

What type of connective tissue is characterized by a gel-like matrix and a variety of cells and fibers?

Loose connective tissue.

Where is dense regular connective tissue commonly found?

In tendons and ligaments.

What is the function of adipose tissue?

Stores energy, provides padding, and insulates.

What is fibrocartilage primarily used for?

Resists compression and prevents bone-to-bone contact.

What does skeletal muscle tissue do?

Moves or stabilizes the position of the skeleton.

What types of cells are found in nervous tissue?

Neurons and Neuroglia.

What process involves inflammation followed by regeneration in response to tissue injury?

Wound healing.

How does aging affect tissue regeneration?

Speed and effectiveness of tissue regeneration decrease.
