Histology Lab

Purpose:
To compare & contrast epithelial and connective tissue by observing slides and identifying structures.
Materials:
Microscope, 6 slides- Simple Cuboidal, Simple Columnar, Transitional, Areolar, Osseous, Hyaline Cartilage
Procedure:
1. Set slide on stage and fasten it with the stage clips
2. Starting from the scanning lens move your way through the objective lenses using the coarse focus knob (on the Objective) and finally the fine adjustment knob (on the low and high power)
3. Take a picture of your findings

Name of Tissue
Type of Tissue
Location on Body
Function
Simple Cuboidal
Epithelial
Kidney Tubules; Ducts and secretory portions of small glands and, ovary surface
Secretion & Absorption
Simple Columnar
Epithelial
Non-ciliated type lines most of the digestive tract (stomach to anal canal), gall bladder and excretory ducts of some glands
Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus by ciliated action
Transitional
Epithelial
Lines the ureters, urinary bladder, and part of the urethra
Stretches readily and permits distension of urinary organ by contained urine
Areolar
Connective
Widely distributed under epithelia of body
Wraps and cushions organs
Osseous
Connective
Skeletal Structures of Body
Support, movement, protection, mineral storage, and blood production.
Hyaline Cartilage
Connective
Forms most of the embryonic skeleton; covers the ends of long bones in joint cavities; forms the costal cartilages of the ribs, cartilages of the nose, trachea, and larynx.
Supports and reinforces; has resilient cushioning properties; resists compressive stress

Conclusion:
Epithelial tissue covers the whole surface of the body and lines the inside of tube and hollow organs. It is observed that it is made up of cells closely packed and ranged in one or more layers. It provides protection, regulates exchange, transport, secrete, the cells touch, act as barrier, ex: lungs, intestine, kidney, exocrine gland, skin, trachea, lining blood vessel. Epithelial tissues are tightly packed group of cells. They protect the body (your skin), absorb nutrients (in
