responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping‚ walking‚ pain perception‚ and other important functions). While the old brain is important‚ it is very limited in what it can

Enkephalins and Endorphins Do you have an experience that you cut your finger‚ it is painful in the few minutes‚ after that‚ it stops that feeling. Do you know why? This related a kind of hormone called opioid peptides. Their function is as j nanalgesic hormones. Opioid neuropeptides were first discovered in 1974 by two independent groups of investigators: John Hughes and Hans Kosterlitz of Scotland isolated — from the brain of a pig，called enkephalins.1 Around the same time‚ in a calf brain‚

Answers: Reproductive cells undergo meiosis Non-germ cells are reproduced Red blood cells undergo meiosis Number of chromosomes reduces by half in phase one Cell divides to produce four daughter cells Response Feedback: Meiosis occurs only in replicating gametes or reproducing cells. In phase one‚ the number of chromosomes is reduced by half but the chromatid pairs remain together. In phase

Myelencephalon The first part of the brain is the myelencephalon. The myelencephalon is also known as the medulla‚ it is made out of large tracts that carry signals between the rest of the brain and the body (Pinel‚ 2011). The myelencephalon has a reticular formation and has about 100 tiny little nuclei’s. What the myelencephalon does for the human body is it plays a role in arousal‚ sleep‚ attention‚ movement‚ muscle ton‚ and various cardiac‚ circulatory‚ and respiratory reflexes (Pinel‚ p.64 ‚ 2011).
