Oh, you noticed this scar on my face...yeah, I fell while exercising and well...now it's here. It sucks 'cause homecoming is 6 weeks away and I'm not sure if it'll be gone by then
Well Tristan, there are four types of tissues in your body: Epithelial, connective, muscular, and nervous.
This is my girlfriend, Meggy. She doesn't feel real great about my scar...do you Meggy?
Each type has its own subtype! For example, Epithelial tissue has simple, stratified, and glandular types.
She loves me I swear...
No, I really don't actually. I mean, how're are we supposed to take good pictures if you have THAT on your face?!
Oh. hey Mr. Johnson!
Hey Tristan! Meggy told me that you have some questions about scarring? You can come into my classroom if you want to know more.
So, Mr. Johnson...I keep hearing about tissue types and which scar...what are they?
The subtype to that subtype include squamous, cuboidal, columnar, and pseudostratified columnar. They are all surface cells, but sqamous are flatter w/ a single layer of 'em, while cuboidal are shaped like cubes and columnar are shaped like rectangles aligned in a column.
Simple Epithelium surface tissue is used to assist filtration, diffusion, secretion and absorption; these cells are found on the skin of the body- like where your scar is- along with the surfaces of body cavities(viscera, glands, and all tubular organs).
Lemme tell you where they're found! Squamous are located on the lining of the heart, the internal surfaces of all blood and lymph vessels.
Cuboidal are secretory cells found in the tubules of tje kidney, while columnar can be found linging the gastrointestinal tract- dealing with secretion and absorption
Lastly, pseudostratified columnar cells are bunched up to assist with secretion, and are located in the lining of reproductive tracts and air conduction pathways of the respiratory tract. It's quite fascinating isn't it?!
