The dendrites particularly receive the impulses and they convey the impulses to the neuron whereas the axon carries the impulse away from the neuron to its respective destination. The human brain is divided into two hemispheres, and within each hemisphere, there are four lobes namely; frontal lobe, parietal lobe, temporal lobe and occipital lobe (Goldberg & Sacks 2001; Snell 2006).
Frontal lobe lies in front of the cerebral hemisphere. Cerebral hemisphere is divided by four sulci which are the central sulcus, lateral sulcus, parieto-occipital sulcus, and calcarine sulcus. Frontal lobe lies anteriorly to the central sulcus and superiorly to the lateral sulcus. The frontal lobe helps in the motor functions of the body along with cognitive functions. An area known as the precentral area is located in frontal lobe which receives connections from the somatosensory area of the parietal lobe. This area helps in the initiation of motor functions. Broca’s area is also located in the frontal lobe which helps in the speech function of individuals. The frontal lobe is also known to help in the cognitive processes of thought and learning. Personality is also determined because of the areas which are located in the frontal lobe. It is connected to other parts of the brain through association fibers which are discussed subsequently. Many other areas like supplementary motor area, frontal eye field, and prefrontal cortex are located in the region of the frontal lobe (Waxman 2009; Carlson & Carlson 2010).
The frontal lobe is located at the front of each cerebral hemisphere. The superolateral surface of the frontal lobe has three sulci which divide it into four gyri. Gyri are the folds of the brain which increase the surface area of the brain and the folds are separated from each other by sulci.  ...Download file to see next pagesRead More

Nervous System description

...consists of nerves and the wiring. The major function of central nervous system is to collect information and send out instructions. On the other hand, peripheral nervous system collects the information from the central nervous system and distributes it to the rests parts of the body. Human central nervous system contains brain, spinal cord, and retina whereas the human peripheral nervous system consists of sensory neurons, clusters of neurons (ganglia) and nerves connecting to the central nervous...

Functions of the different parts of the nervous system

...?All About the Brain The Central Nervous System is a very interesting part of the human body for it controls most of the body’s activities- consciousor otherwise. One of the most important parts of the CNS is the brain. Although there are many resources that can provide information about the brain, The Society for Neuroscience provides materials that are easy to read for the general public. The first thing I downloaded was the e-book “Brain Facts” in PDF format. The main contents of the book covered basic topics that one needs to know about the brain such as: neuron, brain development, sensation and perception, learning, among many others. Each section discussed definitions, processes or simply explained components of the brain... on how...

Nervous system

...?The Brain The nervous system is the most important system in the human body. It is in charge of coordinating all aspects of the body from processes such as our heart beating to typing a paper. This is achieved through a network of extensive neurons, which are located throughout the body with the highest concentration residing in the brain. Communication is achieved through electrochemical signals, which cause a release in neurotransmitters. The brain is a highly organized structure with sections called lobes. The lobes are the temporal lobe, occipital lobe, parietal lobe, and frontal...

...of neurons and the brain. This system is very important in that it helps in receiving, sending, and conceptualizing data from all parts of the body. Further, just like discovered in the practical, the nervous system reacts to transformation in the outside environment, and helps monitor and coordinate internal work of body organs. The spinal cord has nerves that assist in transmitting information from body organs and outside environment to the brain and directs data from the brain to the rest of the body. The spinal cord nerves are fiber like that travel in two distinct manners. Descending nerves carry data concerning the motor function from the brain to...

...actions like the likes of sneezing, coughing, vomiting and swallowing etc (J. K., et al., 1997).. These tasks are further subdivided into different other parts which are associated to the Autonomic Nervous System (ANS) subsystems and the overall nervous systems that are outside of the brain. The hypothalamus that is situated just above the brain stem basically serves the purpose as an integrator for the different autonomic functions of the body, and receives Autonomic Nervous System regulatory input from the limbic system to manage its role as the integrator (University...

The Autonomic Nervous System

...? The Autonomic Nervous System The autonomic nervous system derives its from two words, ly auto meaning self and nomo which implies govern. Therefore, the autonomic nervous system controls the involuntary activities of the smooth muscles and several undertakings o the glands. It forms a component of the peripheral nervous system and can be subdivided into two categories. These include the sympathetic and parasympathetic nervous system. In all these categories are comprised of effector neurons which connect the central nervous system top their effector organs. Each pathway comprises of a preganglionic neurone as well as a postganglionic neurone. Within the sympathetic system, the synapses between these two neurons are located near... the...

Central Nervous System

...Central Nervous System Central Nervous System Question Sensorineural hearing loss is where the cause of hearing loss originates from the vestibulocochlear nerve, the interior ear (Hoehn & Marieb 2010, 543). Conductive hearing loss, in contrast, happens when there is an issue of conducting sound waves along the route through the outer ear. In the Rinne test, with regards to Sensorineural hearing loss, one can expect to find the air condition and bone equally reduced. Also, the results that a person can expect to find with this test are normal. Finally, with regards to conductive hearing loss and the Rinne test, a person can expect to find the conditions of the bone and...

... does is not tied to the experience of the individual (McDowell, 2011). An individual’s experience is an interpretation of sensory inputs that is carried out by nervous system processes that are normally unknown and unpredictable to a degree. In addition, an external observer will consider the self to be a complex and evolving blend of internal and external experiences. This bipartite arrangement is responsible for concepts like agency, freedom, and individuality in persons (McDowell, 2011). The nervous system is an explorer as a whole, while its distinguishable parts are also explorers, as well. In addition, exploration and interpretation are different with regards to the whole nervous system and its distinguishable parts... that...

Nervous system

...Nervous System: Describe how you will perform a neurological assessment. A patient with unilateral facial drooping should be neurologically assessed for all cranial nerves. The patient should be asked if she has any trouble smelling or tasting. She should also be asked to follow the finger of the examiner which is held out in front of her between her eyes. She should be asked to give a broad smile. She should be asked to widely open her mouth so that the examiner could check the movement of uvula. She should be asked to protrude her tongue and then, it should be noted if the tongue deviates to left or right. Determine if upper or lower neuron disease is the cause of her complaint. The patient’s face in...

Nervous System Anatomy Senses

.... A. An afterimage can be explained as a false image perceived by the human eye when the person shifts away his view from the object or image but can still see it for a fraction of a second. The origins of visual after images are believed to be lag in the sensory nerves of the human beings to register quick visual changes in the surroundings. Q4. Describe the relationship between hearing and balance.  A. Hearing and balancing are inter related as ears not only control hearing but also balance; therefore any hearing deficiency can lead to problems with balancing. Problems with hearing can result in failure to register movements, which can eventually create issues with balance. Reference Dean, C., Rosen, S., Mathe, E., Bjur, M.,...
