Anatomy and Function of Basic Tissue Types: Epithelial, Connective, Muscle, and Nerve - Pr, Study notes of Physiology

An in-depth exploration of the four major types of tissues in the human body: epithelial, connective, muscle, and nerve. Each tissue type is characterized by its structure and function, and the document covers the various subtypes, characteristics, and functions of each. Epithelial tissue, for instance, covers surfaces and forms glands, while connective tissue provides support and binds other tissues together. Muscle tissue enables movement, and nerve tissue transmits electrical signals.

Four Basic Tissue Types

Classified by Structure (shape, cell

relationships, extracellular matrix…)

EPITHELIAL

CONNECTIVE

Classified by Function

MUSCLE

NERVE

EPITHELIAL TISSUE TYPES

Squamous (flat)

  • Cuboidal (square/cube-shaped)
  • Columnar (taller than wide)

Urethra

GLANDS

Two Types:

Exocrine--secretes products onto body surfaces or into

body cavities (generally through ducts)

  • classified according to numbers of cells, shape,

branching…(simple vs. compound; acinar, tubular,

alveolar)

  • Unicellular—Goblet Cells (mucin)
  • Merocrine--products only (e.g., sweat glands?)
  • Apocrine--products + gland cell fragments; secretory cell repair

(e.g., mammary glands???Merocrine???)

  • Holocrine--products + cells; secretory cell death

(e.g., sebaceous glands)

Endocrine--secretes products directly into

interstitial spaces; without ducts (Ch. 16)

Acinar glands

APOCRINE???

MEROCRINE APOCRINE HOLOCRINE
