Exocrine Glands

-Ducts- Branched or unbranched

-Shape of the secretory portion of the gland

Descrive the General make- up of a tissue

Common embryonic origin

Function together to carry out specialized activities

Four primary Tissue types

Epithelial

Connective

Muscular

Nervous

Major Function Of Epithelial Tissue

Covers body surfaces and lines hollow organs, body cavities, duct, and forms glands

Function of Connective tissue

~Enclosing and Separation other tissues

~Connection tissues to one another

~Supporting and moving parts of the body

~storing compounds

~cusiniong and insulation

~transporting

~protecting

Epithelium

Simple Squamous

~Filtration or diffustion

Simple Cubodial

~Thyroid gland and kidneys

~Secretion and absorption

Simple Columnar

~Secrete mucus

~Ciliated or contain Microvilli

Pseudostratified

~All cells attached to basement membrane, but some do not reach apical surface

Types of Epithelial

covering and lining epithelium

Glandular Epithelium

Endocrine

~Secrete hormones into blood stream

~important in Homeostasis

Exocrine

Secretes mucus into ducts that empty onto the surface of epithelium

Glands based on structure

Branched or unbranced

Shape of the secretory portion of the gland

Merocrine gland

cells of the gland produce secretions by active transport

~ Produce vesicles that contain secretory products, and the vesicles empty their contents into the duct through exocytosis

Apocrine Gland

secretory products are stored in the cell near the lumen of the duct. A protion of the cell near the lumen containing secretory products is pinched off the cell and joins secretions produced by a merocine process

Holocrine

Secretory products are stored in the cells of the gland.

Entire cells are shed by the gland and become part of the secretion. The lost cells are replaced by other cells deeper in the gland

Connective TISSUES

~Enclsoing and separating other tissues

~ Connecting tissues to one another

~Supporting and moving parts of the body

~Storing compunds

~Coushining and insulating

~Transporting

~protceting

Connective tissues cells

Fibroblasts

Secrete fibers and components of ground substance

Adipocytes (fat cells)

Store triglycerides (fat)

Mast cells

Produce histamine

White blood cells

Immune response

Macrophages

Engulf bacteria and cellular debris by phagocytosis

Plasma cells

Secrete antibodies

Three main components of the extracellular Matrix of connective tissue

Collagen

Elastic

Reticular

Explain how adult connective tissue is classified.

amount of collagen present

Give an example of each type of connective tissue; describe its characteristic functions, and its location in the body.

null

Discuss the three types of muscle tissue by describing their general structures, locations in the body, and functions.

null

Describe the functional specialty of nervous tissue.

null

Explain the functions of neurons and neuroglia.
