How the Resting Membrane Potential Has Established - Essay Example

Repolarization: It is a case where neuron membrane potential returns to a negative value, back to resting membrane potential. This is due to the movement of positively charged K+ ions out of the cell which takes less than a second.
Hyperpolarization: This takes place when electrical potential differences occur between two sides across a neuron thus becoming more negative than the outside charge.
Functions of each of the following:

Frontal lobe: It is part of the lobe that controls important skills for humans, such as memory, and emotions. Other responsibilities include primary motor function/ ability to consciously move our muscles and two key areas related to speech.
Parietal lobe: Has the responsibility of processing sensory information which includes taste and touch. Other responsibilities include coordination of eye gaze and verbal memory.
Occipital lobe: It is associated with interpreting information and visual stimuli from the retinas of the eyes.

Temporal lobe: It is associated with the retention of visual memories, processing sensory input, and storing new memories.
Limbic lobe: It deals with three functions: stimulation (arousal), emotions, and memories. It connects parts of the brain that deal with high and low functions.
Thalamus: Its main function is to relay motor and sensory signals to the cerebral cortex regulating sleep, alertness, and wakefulness.

Hypothalamus: It is responsible for hormone production. The hormones produced govern the body's thirst, sleep, sex drive, and homeostasis in the body.
Pituitary gland: Generates prolactin enabling new mothers to produce milk. It is also involved in the development of the body, reproduction, and sexual maturation.
Midbrain: Serves the function of being a path between the forebrain and the hindbrain. In addition, it controls functions such as hearing, eye/body movement, and vision.
Pons: Is involved in motor sensory and control analysis.

Medulla: It maintains vital body functions, such as heart rate and breathing.

Question 4
Some of the things we say to our friends are misinterpreted and they come up with their own stories. Recently my co-worker requested me to accompany her to a dinner out of the city, which I declined with a good reason. The reason I declined the deal was that I was supposedly attending another concert, and being the organizer, I had to see that all went well throughout the event. Unfortunately, we later met with the same colleague while in the company of another lady friend. Contrary to my expectations, the colleague assumed that I had turned down her deal for a better one. I was not in a position to explain what happened at that moment, but fortunately, I did later. It is thus true that it is not what is intended, but what are perceived matters.

Type 2 diabetes
A type 2 diabetes treatment for newly diabetic patients recently has grown in complexity. Some of the older therapies continue to be supplemented by the new ones. Emerging research compares effectiveness and safety while monitoring these patterns critically. Some of the emerging trends include new classes of devices adding and drugs, thus improving the lives of type 2 diabetes patients. The condition can also be treated by learning how to exercise and choosing the right diet. Doctors are becoming more vigilant in treating diabetes. The current medical expertise is helping type 2 diabetes patients to be diagnosed and treated earlier than they once did. These trends like new medications advanced eating habits and new drug research through available technology will help combat this epidemic. Read More
