List the four functions of the epithelial tissue: Answer may include any three of the following: protection, sensory functions, secretion, absorption, and excretion.
How do exocrine glands secrete their products? Exocrine glands discharge their secretion products into ducts.
Name three kinds of fibers that may be present in a connective tissue ECM. Of what are they made of? Collagenous fibers: white fibers made up of collagen and often occurring in bundles. Reticular fibers: made up of a specialized type of collagen called reticulin. Elastic fibers: made up of a protein called elastin.
Name four types of fibrous connective tissue and briefly describe each: Loose connective tissue, Adipose connective tissue, Reticular connective tissue,Dense connective tissue.
Connective tissue #1 Loose connective tissue: : stretchable, and one of the most widely distributed of all tissues. The matrix is a soft, thick gel. Contains many fibroblasts and macrophages.
Connective tissue #2 Adipose connective tissue: contains predominantly fat cells and many fewer fibroblasts, macrophages, and mast cells.
Connective tissue #3 Reticular connective tissue: dense, net-like tissue with branching reticulin fibers with reticular cells. Filters injurious substances out of blood and lymph.
Connective tissue #4 Dense connective tissue: fibers packed densely into a matrix that contains relatively few fibroblast cells. Designated regular or irregular.
What makes bone tissue so hard? The inorganic (bone salt) portion of bone makes it hard.

Which of the two of the four major tissue types have the greatest capacity to regenerate after an injury? Epithelial and connective tissue have the greatest capacity to regenerate after an injury.
Name the four principal types of body membranes. Which are epithelial membranes? Cutaneous, serous, and mucous and connective are the four principal types of body membranes. Cutaneous, serous, and mucous are epithelial membranes.
Name the two main cell types found in the epidermis. Keratinocytes and melanocytes are the two main cell types in the epidermis.
Which layer of the dermis forms bumps that produce ridges on the palms and soles? The dermal papillae forms the bumps that produce ridges.
What is the main function of the hypodermis? ?F? The hypodermis forms a connection between the skin and the underlying structures of the body.
List seven functions of the skin. Protection, sensation, growth, synthesis of important chemicals and hormones, excretion, temperature regulation, and immunity are the functions of the skin.
