Sensory system

(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

between the Central Nervous System (CNS) and Peripheral Nervous System (PNS)? Discuss the activities the nervous system is responsible for. In my research about the differences of the central nervous system and the peripheral nervous system is that the central nervous system, also known as CNS, controls the entire body. The central nervous system deals with the brain and spinal cord. It also controls everything we need to survive on a daily basis. The central nervous system consists of our…

parasympathetic division of the autonomic nervous system The autonomic nervous system (ANS) is a part of the peripheral nervous system that largely acts involuntarily. It consists of nerves in cardiac muscle, smooth muscle, exocrine and endocrine glands. The main visceral activities are temperature regulation, digestion, blood pressure and genitourinary function. The second main division of the peripheral nervous system is the somatic nervous system. This consists of cranial and spinal nerves…

this? The Central Nervous System contains the brain and spinal cord which gathers and organizes information. The Peripheral Nervous System encompasses all other nervous system tissue. Sensory receptors and neurons along with motor neurons are components of the Peripheral Nervous System which follows the commands of the Central Nervous System. The bones of the skull and spinal vertebrae house all of the Central Nervous System neurons. Neurons in the Peripheral Nervous System are not surrounded…

different processes to return the body back to normal and stable. The body is complex with multiple organ systems, but this essay will explain how the different parts of the nervous system and its relationship with other organ systems maintain homeostasis. The nervous system has three parts that work together, the central nervous system (CNS), peripheral nervous system (PNS), and autonomic nervous system (ANS), which are further divided and each division…

The major role of the HPA axis is to mediate the neuroendocrine stress response, in order to reestablish body homeostasis after an acute stressor (4).A principal component of the stress response is the CRH system, which is located in the paraventricular nucleus (PVN) of the hypothalamus. CRH is synthesized by neurons in the parvocellular/small cell division of the PVN, and it is secreted into the pituitary portal blood (5-7). CRH via portal blood enters the anterior pituitary and binds to type 1…

innervated by the Chorda Tympani branch of the Facial nerve which is carried by the lingual nerve which branches off the mandibular branch of the Trigeminal nerve. Sensory component of the anterior 2/3 is maintained by the lingual nerve. The posterior 1/3 of the tongue is innervated by the glossopharyngeal nerve which supplies both sensory and taste. B. The human tongue contains multiple types of taste buds. These include:fungiform,foliate,circumvallate,filiform papillae. These papillae are…

Micheal Merzenich was one of the world leading researcher on brain plasticity and famous for his innovation and practical inventions in Neuroplasticity. His works mostly involve brain mapping, where brain is trained to think and process information differently. He believed doing the brain exercise is similar to taking drugs to treat brain diseases. He cured some disorder that once thought incurable. He is the first one to design the cochlear implant that allow deaf children to hear. He designed…

Laura’s grandfather has begun having memory problems. First, he would constantly forget where he placed his keys or his wallet. Then he would have trouble remembering to pay the bills or cooking dinner. One day, Laura took him shopping, and in the middle of the trip, while they were both using the restroom, Laura’s grandpa left. Laura spent many hours searching for him in the shopping area, but to no avail, she could not find him. When she returned home, she found him sitting on the couch, and…

prevention of the rabies virus. What is rabies? Rabies is a type of zoonotic disease. A zoonotic disease is a disease that is transmitted by animals to humans. According to the Merian-Dictionary, the rabies virus is an acute virus disease of the nervous system of warm-blooded animals that is transmitted by infected saliva usually through the bite of a rabid animal ((n.d.). Retrieved from http://www.merian-webster.com/). In the Latin language, rabies refers to rage or madness…
