Summary Introduction
To trace:
Each step in the pathway from an external acoustic meatus to the hearing receptor.
Introduction:
The mechanoreceptors present in the ear detect the sense of sounds. The ear is the organ which is used for hearing in mammals. The outer ear comprises the structure that is present externally. The structures present in the outer ear are pinna (auricle), S-shaped tube, external acoustic, meatus (external auditory canal) and the tympanic membrane (eardrum).
Pictorial representation:
Fig.1:Flow diagram of the pathway of the sound wave from an external acoustic meatus to the hearing receptor.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.
