Cells of the body are organized into four fundamental tissues; epithelial‚ connective‚ muscle and nerve. Epithelial tissues line all surfaces of the body: the skin‚ cavities‚ ducts‚ vessels. They are named according to the cell shape on the free surface. Cells of a tissue are held together by the basement membrane and intercellular fibbers. These tissues receive their nutrition by diffusion‚ for they are without blood vessels. Simple squamous epithelium lines all blood and lymphatic vessel‚ including

Practical 1 Title: Tissue Processing Aim: To examine human cell and tissue under the microscope Introduction: Tissues from the body taken for analysis of diseases must be processed in the histology laboratory to produce microscopic slides that are viewed under the microscope. These tissues are usually fixed into paraffin. Microscopic analysis of cells and tissues requires the preparation of very thin‚ high quality sections mounted on glass slides and properly stained to demonstrate normal and abnormal

Alvaro Comino LAB REPORT 4 CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II. Introduction Apart from the bone and cartilage‚ the rest of the specialized connective tissues are divided

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

and centrifuged for 20 seconds. A polyacrylamide gel was assembled and the samples were loaded into it. The gel ran for approximately 45 minutes at 160 V. A western blot analysis was done in order to examine the Erk1/2 phosphorylation of the NIH3T3 cells. Three pieces of Whatman paper were wet in transfer buffer and placed on the anode plate. A wet PVDF membrane was placed on top of the Whatman paper. The gel was removed from holder and the stacking gel was removed. Forceps were used to place the gel

Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution
