What does an epidermal cell do?
The two main functions of the epidermis (or the skin) are: 1) A barrier against pathogens and toxins. - The epidermis acts as a physical barrier but also as a chemical barrier due to the presence of lipids and acids which work to destroy certain pathogens. 2) Hydration - The skin holds a large percentage of water and lipids arranged within the epidermis act as a barrier to prevent water loss from the body.

Why edema is periorbital in nephrotic syndrome?
due to low oncotic pressure of blood and also due to increase in permeability of vessels of most tissues along with basement membrane of kidney.
What factor is responsible for the increase in the permeability of the cells of the collecting tubule to water?
Increase in permeability of the cells of the collecting tubule to water is due to an increase in the production of antidiuretic hormone (ADH). Aquaporins are constant components of the tubule cells membranes. Unless ADH is present, aquaporins are virtually absent in the luminal membranes of the collecting duct.A decrease in the concentration of the blood plasma
What is the result of parasympathetic stimulation of the SA node?
Action potentials will occur less often due to an increase in the membranes permeability to K+
Does the rate at which a rock undergoes chemical weathering increase or stay the same when the rock becomes more mechanically weathered why?
The rate will increase due to the increase in surface area available for attack by chemical weathering.
Potential sources of error in experiment permeability test falling head method?
1. The permeability results might be localized due to excavation. 2. Lateral permeability not considered which may lead to erroneous estimate of field permeability.
What is syncytial epidermis?
Epidermis containing cells which have many nuclei formed due to fusion of many cells.
What are prostoglandins?
Prostoglandins are chemical mediators. These are released from mammalian cells and effect the cells in their immediate viccinity. They produce what's known as an inflammatory response. Prostoglandins are found in cell membranes, they are released due to injury. They cause the dilation of small arteries and arterioles and increase the permeability of the capillaries. They affect neurotransmitters and blood pressure and hence pain sensation.
