Running head: the nervous system The nervous system The nervous system is divided into central nervous system and peripheral nervous system depending upon their anatomy and functions. The two most important components of the central nervous system are brain and spinal cord. The brain plays key role in controlling behavior (Carlson, 2011). The brain reacts in response to external stimuli passed on by the components of peripheral nervous system. The PNS comprises of somatic and autonomic divisions. The somatic divisions are made up of sensory neurons that are involved in passing external stimuli to the brain from skin, muscles and joints. The autonomic division is made up of motor neurons which connect skeletal muscles with the central nervous system, thereby coordinating and controlling functioning of various organs. The brain and spinal cord together control all body functions, behavior as well as body movements in coordination with the peripheral nervous system. The CNS and PNS are interdependent for effective functioning. Besides these, various parts in the brain are involved in memory-related activities because of which the brain is very important part as memory leads to cognition and human learning. The brain also aids in reasoning, thinking, recognizing and other cognitive activities (Carlson, 2011). Yet, the brain receives stimulus for memory from the sensory neurons of the PNS. The spinal cord’s function is to coordinate muscle movements and cause body or muscle reflexes to external and internal stimuli. All these functions are carried out through structures within each component that are highly complex and are made up of nerve cells or neurons. Hence, the most important components of CNS are brain and spinal cord and that of PNS include sensory and motor neurons. References Carlson, N. (2011).

Nervous System description

...? Nervous System Nervous System (Human nervous system, n. d) The nervous system is one of the vital organ systems in animals which transmit signals between different parts of the body. All the organs in our body rely nervous system heavily for their functioning. Just like the central processing unit of a computer, nervous system can be considered as a master control unit inside our body. Basic function of nervous system is the controlling and coordination of body functions. It receives...

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 lobes. Each is charged with a specific cognitive function and even though they are...

...? THE NERVOUS SYSTEM From the practical conducted, it is clear that blowflies lay their eggs on decaying material, such as the carcasses of dead animals. Larvae hatch from eggs and this is a temperature dependent process. Larvae – the maggots - have an outer cuticle and an inner epithelia basement membrane (Sawin, Harris, Campos, & Sokolowski, 1994, p. 353). The cuticle is 5µm thick in young larvae (36 hours, first instar), 25µm in 60-hour-old larvae (second instar), and 40µm in last (third) instar larvae. Maggot behavior is linked to instar development; for example, in the first and second instar the maggots stay close together and feed, but in the third instar, they move away from each other and seek a safe placement for pupal... ...

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...

The Sensory Nervous System

...Perception of stimulus- Role of Central and Peripheral nervous systems The increased complexity of the human body, brought about by evolution, alsoincreased the need for co-ordination and control of the various parts of the body. This is brought about by the nervous system. There are two distinct sections of the human nervous system, the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system comprises of the brain and the spinal cord, whereas the peripheral nervous...

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...

... that nervous system modules are active local circuits, rather than mere anatomical entities. During construction, the specific activities that characterize each module are dependent on both extrinsic and intrinsic neuronal components, its phylogenetic history, and functional roles (Paxinos & Mai, 2013). Numerous intra-cellular and cellular phenomena that are common in most vertebrates underlie how the modules are constructed. In fact, the glial and neuronal interactions, as well as how they interplay with extra-cellular space environment is dependent on molecular families that have broad phyletic occurrences (Paxinos & Mai, 2013). The construction mechanism is accountable to a large degree on for the immense widespread incidence... ...

...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.,...
