#2 Describe in detail the structure and function of any of the following: the nervous system, the brain, the endocrine system. Include charts with you description if you desire.
Simple moments, decisions or reactions all have one thing in common, the brain. The brain is the control center for human’s entire body, giving signals at all times on what to do or how to respond. Nerves that connect your body to the brain are responsible for gather information to give to the spinal cord to give to the brain so that it can make sense of the message. The adult brain weighs about 3 pounds, and is made of three major parts: the forebrain, midbrain and hindbrain. The forebrain is divided into three more parts called the cerebrum, thalamus, and hypothalamus …show more content…
By looking at early skulls, we can see evidence about the volume of these ancient brains and compare them to modern day measurements. The early Homo sapiens had a volume of brain in the same rage of humans today at about 1,200 ml. When the homo sapiens linguistic complexity, dietary needs and technological advances increased rapidly, the brain grew to accommodate these new skill sets. Ironically within the past 10,000 years of human life, our brains have diminished in size. But while the size changes, the brain's structure remains similar while the function of certain sections is adapting to modern day situations.
The frontal lobe is the most recently-evolved section of the brain as well as the last to develop in the transition to adulthood. This section serves as the brain’s top executive. It’s function is to organize the responses to complex problems, develop strategies to coordinate with new data, and also guiding the behavior with verbal skills. Inside the frontal lobe, the orbitofrontal circuit is delegated to managing emotional impulses in socially appropriate ways. If one were to have a stroke in this area, skills such as impulse control are often lost resulting in foul language and foutous behavior …show more content…
Shaped like an almond, the amygdala's duty is to constantly keep alert for needs of basic human survival. These needs include but are not limited to sex, emotion reactions (anger, fear,sadness,etc). The amygdala also triggers aversive cues such as sweaty palms in response to high tension situations. The amygdala helps to process memories in a way that is beneficial to survival. For example in one was bitten by a dog, the amygdala would process that event as distressing, resulting in an increased alertness around dogs in the future. Due to its highly emotional nature, the amygdala is positively correlated with increased aggression and physical behavior
The brain stem is one of the most important parts of the brain. It serves as a connection between the motor and sensory systems of the corext, and acts a s bridge to communicate with the peripheral nervous system The brain stem is also responsible for many basic functions such as in regulating of heart rate, breathing, sleeping, and
