They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception. Where are epithelial tissues found in the body? What are some of the features of the dermal papillae that you observed on this slide, and how do those features affect the surface of the skin? Stratum Corneum: Provides structural strength due to keratin within cells; prevents water loss due to lipids surrounding cells; sloughing off of most superficial cells resists abrasion.

I would more easily be able to identify the shape Hair also aides in thermoregulation. Which type(s) of epithelial cells have a basal lamina? A slice of the colon, 20x.. Emerging studies have revealed that long noncoding RNAs (lncRNAs) contribute to HCC progression. 0 Adipose Tissue -Densely clustered adipocytes at 100x. Epithelial tissue has a variety of functions depending on where it's located in your body, including protection, secretion and absorption. protects, and gives structure to other tissues and organs in the body. D. Where is connective tissue found in the body? The cells will usually be one of the three basic cell shapes squamous, cuboidal, or columnar. Differences: Stratum Basale layer is comprised of cuboidal cells, Stratum spinosum has prickle, cells that protect against pathogens, Stratum Granulosum contain lamellar granules, Stratum, lucidum contains proteins that give the effects of being translucent making it hard to identify.

In every case, you have to find which edge has the epithelial layer. List three areas where connective tissue is found in the body? Skeletal -Is cylindrical in shape, is voluntary, and striated. Dense Irregular Connective Tissue -Looks like the tissue goes everywhere at 100x, can clearly see the collagen fibers and fibroblasts. Why or why not. Find the stage controls and make sure that, when they are turned, the slide moves smoothly left and right or up and down, depending on the knob. If you need further magnification, move to the next highest power objective and use only the fine focus to get your image into perfect focus for your eyes. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue.. Provided by: OpenStax College. Squamous cells are comprised of a single layer of flat cells which can be found in the lining of the heart, lungs, and blood vessels.

Black arrows in left panel indicate organelle in pulmonary epithelial cell. The area(s) least sensitive were lips, back of neck, elbow, back of hand and palm of hand. Move your hand to the fine focus knob and get the specimen into perfect focus for your eyes. Stratified columnar cells can be found in the lining of large ducts. -Nutrients, oxygen, and waste products must be transported to and from epithelial tissue by diffusion because it lacks blood vessels. and skin protection. , 7.

Stratified has two to the skin Somas: AKA neuron cell body. # I believe the reason there are more sweat glands in the right palm is because it is an area that is readily exposed allowing sweat to escape the skin unlike the anterior thigh that is mostly covered.
