Anatomy Structure & Function: Tissues

A collection of flashcards covering key concepts related to the anatomy and function of tissues, including types of epithelium, connective tissue characteristics, muscle types, and nervous tissue.

Histology

The study of tissues.

Epithelium

A type of tissue that lines internal and external body surfaces, is avascular, demonstrates polarity, has a high regeneration rate, and is highly cellular.

Simple Squamous Epithelium

A single layer of flat cells found in locations like alveoli and blood vessel linings, facilitating diffusion.

Mesothelioma

A cancer of the mesothelium often caused by asbestos exposure.

Connective Tissue Characteristics

The most abundant tissue that supports and binds other tissues, made up of cells, fiber (collagen, elastic, reticular), and ground substance.

Adipose Tissue

A type of connective tissue dominated by adipocytes, involved in lipid storage.

Skeletal Muscle

Striated, voluntary muscle with long, multinucleated cells responsible for locomotion and heat production.

Smooth Muscle

Involuntary muscle characterized by small, tapering, single-nucleus cells, functioning in organ movement.

Cardiac Muscle

Involuntary, branched, striated muscle that pumps blood through intercalated discs.

Neurons

Cells in nervous tissue that send electrical impulses.

Neuroglia

Support cells in nervous tissue that assist and protect neurons.

Transitional Epithelium

Epithelium that changes shape to accommodate volume changes, found in the bladder.

Cystic Fibrosis

A pathology where thickened mucus impacts respiratory and digestive systems.

Pseudostratified Ciliated Columnar Epithelium

A type of epithelium found in the respiratory tract, responsible for mucus secretion and propulsion.

Collagen

A protein fiber found in connective tissue that provides strength and structure.
