1. TISSUES: The Living Fabric
Tissue - a group cells similar in structure and function
Histology - the study of tissues; requires a light microscope to examine

2. EMBRYONIC GERM LAYERS
Endoderm - functional linings of the digestive and respiratory tract; accessory organs and glands such as lungs, stomach, pancreas
Mesoderm - skeletal system, muscular system, and circulatory system
Ectoderm - epidermis of the skin and all components of the nervous system

Epithelia=forms sheets or layers of cells that line the body tubes, cavities, or coverings of the body surfaces.
Glands=formed of epithelial cells with secretory functions.

27. GLANDULAR EPITHELIUM
Endocrine glands= “ductless” glands that produce hormones. Secrete directly into interstitial fluids or bloodstream. Examples: pituitary gland, adrenal gland, thyroid gland, etc.
Exocrine glands=glands possessing ducts. Exocrine glands secret their substance either on the body surfaces or within ducts.

36. CHARACTERISTICS OF CONNECTIVE TISSUES
Common Origin
Connective tissues vary widely in appearance and function but all forms share three basic components:
Specialized cells
Extracellular protein fibers
Ground substance

38. CHARACTERISTICS OF CONNECTIVE TISSUES
Common Origin
Connective tissues vary widely in appearance and function but all forms share three basic components.
Many types of connective tissue are highly vascular and contain sensory receptors that detect pain, pressure, temperature, and other stimuli.
