Microscopy

The process of using a microscope to view samples, including the steps of fixing, slicing, and staining tissue.

Epithelial Tissue

A type of tissue that covers body surfaces, lines cavities, and forms glands, characterized by closely packed cells and a basement membrane.

Simple Squamous Epithelium

A type of epithelial tissue consisting of a single layer of flat cells that allows fluid movement through air sacs and blood vessels.

Exocrine Glands

Glands that secrete their products through ducts onto external surfaces or into cavities.

Endocrine Glands

Glands that secrete hormones directly into the bloodstream without the use of ducts.

Multicellular Exocrine Glands

Glands composed of many cells that can be classified as simple or compound based on their structure and secretion method.

Collagen Fibers

Protein fibers present in connective tissue that provide strength and support.

Adipose Tissue

A type of connective tissue that stores energy in fat cells.

Skeletal Muscle

Voluntary, striated muscle tissue attached to bones, responsible for body movement.

Nervous Tissue

Tissue that makes up the nervous system, composed of neurons and glial cells, responsible for carrying electrical and chemical impulses.

Cutaneous Membrane

The skin's outer layer, which is dry and keratinized.

Mucous Membranes

Membranes that line body tubes and passages, characterized by wet epithelia that secrete mucus.

Tissue Repair

The process involving inflammation, organization, and regeneration after a wound occurs.

Granulation Tissue

New connective tissue and tiny blood vessels that form on the surfaces of a wound during the healing process.

Fibroblasts

Cells in connective tissue that produce collagen and help in the healing and repair of tissues.
