Histology

The study of tissues and their cellular components.

Epithelium

Tissue that covers and lines surfaces of the body and organs.

Connective Tissue

Tissue that supports, binds, and fills spaces between organs and tissues.

Muscle Tissue

Tissue that contracts to produce movement.

Nervous Tissue

Tissue that conducts electrical impulses and carries information.

Avascular

Referring to tissues that do not contain blood vessels.

Merocrine Secretion

Secretion where no part of the cell is lost during the process.

Apocrine Secretion

Secretion where the apex of the cell is lost with the secretion.

Holocrine Secretion

Secretion where the whole cell detaches and disintegrates to release its product.

Gland

A group of specialized epithelial cells that secrete products onto surfaces or into the blood.

Endocrine Glands

Glands that secrete hormones directly into the bloodstream.

Exocrine Glands

Glands that secrete substances via ducts to an external surface.

Neurons

Specialized cells responsible for transmitting signals in the nervous system.

Glial Cells

Supportive cells in the nervous system that protect and support neurons.

Serous Membrane

Membrane that lines body cavities and covers organs, reducing friction.

Mucous Membrane

Membrane that lines cavities that open to the external environment.

Cutaneous Membrane

The skin, which protects the body surface.

Extracellular Matrix

A network of proteins and molecules that provide structural support to connective tissue.

Fibroblasts

Cells that secrete collagen and other fibers in connective tissue.

Chondroblasts

Cells that produce cartilage.

Osteoblasts

Cells that produce bone matrix.

Hematoxylin and Eosin (H&E) Stain

A common staining method used in histology to differentiate nucleic acids and proteins.

Immunohistochemistry (IHC)

A method to visualize cellular components using specific antibody-antigen interactions.
