Histology (Tissues)

These flashcards cover key vocabulary and concepts related to tissues in histology, designed to aid in studying for exams.

Tissues

Groups of similar cells with a common function.

Histology

The study of tissues.

Epithelial Tissue

Covers organs and body surfaces, lines cavities and hollow organs, and makes up glands.

Connective Tissue

Binds, supports, and protects other tissues; fills spaces, stores fat, and produces blood cells.

Muscle Tissue

Tissue responsible for movement.

Nervous Tissue

Tissue that conducts impulses for coordination, regulation, and sensory reception.

Simple Squamous Epithelium

A single layer of thin, flat cells, found in areas of diffusion and filtration.

Simple Cuboidal Epithelium

A single layer of cube-shaped cells, specialized for secretion and absorption.

Simple Columnar Epithelium

A single layer of elongated cells that may have goblet cells for secretion.

Stratified Squamous Epithelium

Many layers of flattened cells, providing protection.

Glandular Epithelium

Epithelium composed of cells that produce and secrete substances.

Collagen Fibers

Thick threads of collagen providing tensile strength and flexibility.

Elastic Fibers

Fibers that can stretch and return to their original shape, found in structures like the lungs and blood vessels.

Adipose Tissue

Connective tissue that stores fat and provides insulation and cushioning.

Fibrocartilage

The most durable type of cartilage, providing support and shock absorption.

Hyaline Cartilage

Most common type of cartilage, providing support with a flexible structure.

Nanotechnology

Technology involving structures smaller than 100 nm, used to improve drug delivery across barriers.

Intercellular Junctions

Structures that connect cells, such as tight junctions, desmosomes, and gap junctions.

Merocrine Glands

Glands that secrete fluid products by exocytosis, like sweat glands.

Apocrine Glands

Glands that lose part of their cell during secretion, such as mammary glands.

Holocrine Glands

Glands that release entire cells filled with product, such as sebaceous glands.

Neurons

Specialized cells that conduct impulses in nervous tissue.

Neuroglia

Supporting cells in nervous tissue that nourish and support neurons.
