Write an essay about the four different lobes of the brain.

As far as psychology is concern, the frontal lobe has a major contribution to a person’s emotion, behavior and organization of thoughts. It is considered as the body’s emotional center and home of one person’s personality. The frontal lobe, being an emotional center of the body, regulates most of the dopamine-sensitive neurons in the brain which is associated with drive, attention and planning abilities. The higher thinking skills is also included in the functions of the frontal lobe which allows the person to retain long term memories, determine similarities and differences between things or events and suppress unacceptable social behaviors.

The parietal lobe is located at the posterior of frontal lobe occupying the middle section of the brain. It is considered as the part of the brain which is responsible for tactile sensory perception of pressure, touch and pain. The somatic sensory area is located at the parietal lobe which is responsible for processing of the senses of the body; one of this is recognition of pain, coldness and light touch. The knowledge of a being to the location of his/her body in space as well as the spatial knowledge of a person is synchronized by the parietal lobe. It is also known to have an ability to interpret taste sensation because of the gustatory area.

The Occipital lobe is situated at the back portion of the brain and is connected with interpreting visual stimulus and visual information. It contains the primary visual cortex which perceive and interprets information coming from the person’s eye. The controlling of vision and visual processing done by the occipital lobe of the brain allows us to see and identify the things we are looking at. It also gives us understanding to different colors and shades. Visual interpretation is not only function of occipital lobe, it is also involve in differentiating shapes and understanding different letters and symbols. In a case of head injury and there is a damage on occipital lobe of the brain, the vision of the person will be greatly affected.

D. Temporal Lobe

The temporal lobe is located on around the temples inferior to the frontal lobe. This lobe is the location of the primary auditory cortex which is essential for receiving and interpreting sounds and the language a person hears. It reacts to different kinds of sounds and sound frequencies and helps a being to identify the location of a specific sound. The hippocampus is also situated in the temporal lobe, which is also associated with emotion and formation of memories.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
