The parts of an adult brain that develop from the telencephalon and mesencephalon. Introduction: Brain is one of the major organs of an animal body made up of a large mass of nerve tissues, secured inside the skull. It is involved in various essential functions, such as controlling the blood pressure, heart and respiratory rate. It helps in the maintenance of the internal body environment by regulating the endocrine and nervous system.

Expert Solution & Answer

Explanation of Solution

During the 4th week of development, the brain seems like a rostral part of the neural tube. The expansion and constriction of the brain begins in the 4th week of development. This results in the appearance of its three basic vesicles, namely rhombencephalon, prosencephalon, and mesencephalon. The caudal part of the neural tube develops as the spinal cord.

During the fifth week, five secondary vesicles develop from these three primary vesicles. The five secondary vesicles are telencephalon and diencephalon (from prosencephalon) myelencephalon, and metencephalon (from rhombencephalon). The mesencephalon remains undivided. The telencephalon gives rise to the cerebral hemispheres or cerebrum. The midbrain is formed by the mesencephalon.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. 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.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
