Question - how to interpret or recognize different tissues and cells (epithelium, connective tissue, muscle, and nervous tissue) present in the body.
summary-we were given different slides and we had to figure out different tissues and cells on each slide based on our lab manual reading and understanding.
material- microscope, un-labeled (numbered) slides
Method-
1) get a microscope for your group and connect it to a power outlet. switch on the light.
2) get your first slide (unknown cell) from your TA.
3) put the slide you’re on your mechanical stage and make an adjustment to properly view your slides.
4) you and your partner should take turns to view the slide, and then figure out the slide by discussion and by comparing it with

Slide 6- Goblet cells- found in lungs, and intestinal tissues. The distinguished features are- ovoid in shape, and they are a modification from simple columnar cells.
Slide 7- Elastic Cartilage- found in epiglottis and pinnae.
The distinguishing features- slides had dark purple staining and a have bit tear drop like structure in it.
Slide 8- smooth muscle- found in different organ system like digestive, excretory, respiration and reproductive system.
The distinguished features are- spindle-shaped, centrally located nucleus do not appear striated. Also usually there is a layer where cells are arranged perpendicular to each other.
Slide 9 - simple columnar (ciliated)- found in the intestinal tract, part of the respiratory tract, and uterus. The distinguished features are- A single layer of long columnar cells (width smaller than height) and are ciliated towards the free surface.
Slide 10- hyaline cartilage- found in bronchi and trachea. The distinguished features are glassy matrix, light packed collagen fibers.
Slide 11- skeleton muscles- found around the skeleton. The distinguished features are- cylindrical, and on slides they appears highly striated.
Slide 12- neuron- found in the nervous system. The distinguished features are- branched extension of cytoplasm called the Dendrites and the long thread-like structure called the Axon. slide 13- simple columnar(non-ciliated)- found in the intestinal tract, part respiratory
12. What are the 3 types of cartilage and where would you find each type?
The axons are slender processes of uniform diameter arising from the hillock. There is usually only one unbranched axon per neuron.
1) Apply the stain to your first unknown slide and examine it under the microscope.
• *Describe the 3 main types of cells and the 3 main types of fibers found in connective tissue? Reference Table 5.6.
The fibers in both cells are striated, and the fibers are long and each muscle cell is fused to one another. This is why so many nuclei are included. Also, the fibers are almost threadlike, with dark and light colored striations.
In PowerPoint, use the _____ view to see what each slide will look like when presenting. (Unit 7)
Task2: The main tissue types of the body and the role these play in two named organs of the body.
In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue.

skeleton, which provides the pulling power for us to move around. The main job of the muscular
This series of courses covers the structure of the body’s parts – their forms and how they are organized – and their function, anatomical and disease state terminology.
Consist of the nasal passage, pharynx, esophagus, larynx, trachea, lungs, diaphragm, bronchi, and pulmonary artery and vein.
Cartilaginous joint is connected by the cartilage and is also known is the slightly moveable joint. It allows little movement between joints in places such as the vertebrae and ribs.
It is very (eliminate word for something else) weirdly shaped and is thus very recognizable. The next is that fact that there is a lot of different types of nerve cells and not just one. Also due to this they can be found throughoutappear all around the body, from the spinal cord to the scalp. The nucleus in the cell can be as small as 3 micrometers to 18 micrometers. Another weird fact is that it has a lipid bilayer, which is a very good insulator apparently. Related to insulation and electricity is the fact that the cell produces less than 1/10 of a volt because of interactions between organelles and other molecules in the cell. AnotherNext fact is that no nerve cells lack a soma, but some of them lack an axon or a dendrite, which is a section of the cell that specialises in a certain aspect if it is
