Axon

Nervous System and Diseases Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS)

embraced this idea of a less lethal option to use in force situations. As a potential investor in the Axon company which continues to develop tasers and web based applications for law enforcement it is important to look at the company reports, specifically focusing on the annual financial report from 2016. To begin the process of discerning if Axon is a company worthy of investment I went to the Axon website and downloaded the annual statement for 2016. First, I

in class, from the Human Anatomy and Physiology 9th edition by Marieb and Hoehn (2013), our bodies have billions of neurons, also called as nerve cells. Every neurons contains something called dendrites, which looks like branches, and an axon joined by the axon hillock. The dendrites are part the receives the information from another neuron

cross-bridge formation, comes in filamentous or globular forms. 2. _Synaptic vesicles__ Store neurotransmitters, and following a Ca2+ driven signal, dump neurotransmitters into the synapse. 3. _synaptic terminal__ Th e structure at the end of the axon that contains neurotransmitters and vesicles. 4. _sacromere__ Th e functional unit of the muscle fiber that includes the A-band, I-band, H-zone and the M-line. 5. _sodium__ Th e ion responsible for depolarizing the muscle membrane by traveling

The myelin sheath is where the nerve axons serve as an electrical insulator that speeds up nerve impulses to muscles and other effectors. The damage of the myelin sheath is caused by inflammation of the brain, and may have significant damages to other areas as well. Damaged areas undergo scarring or plaques. Plaques may be found in different areas of the brain, which include: optic nerves, spinal cord, cerebellum, brainstem, and cerebral area of the brain. Researchers have found evidence of damage

main pathway involved in voluntary movement in which neurons originating within the cerebral motor cortex travel relatively long distances to make synaptic connections with lower motor neurons terminating in skeletal muscle (Blackstone et al., 2010). Axons within the cortico-spinal tract are therefore some of the longest motor neurons within the body,

messages are sent and received with neurons through an electrochemical process using their specialized parts axons and dendrites. 1b. On average, our brains contain about 100 billion neurons. 1c. Dendrites are what receive the electrical and chemical messages such as neurotransmitters, and the axons send information and release neurotransmitters. Dendrites are attached to the cell body, and the axon could be seen as a long tail extending from the cell body. 1d. While each person is different, the

The nervous system is home to two major compartments, the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord and the peripheral nervous system contains a total of 43 pair of nerves branching from the spinal cord that distribute signals to the entire body. The neurons that travel through those nerves are divided into two pathways, afferent and efferent. Afferent neurons travel up the spinal cord by entering through dorsal roots and

Introduction The awareness of Traumatic Brain Injuries (TBI) has increased and the information available is better now than it was in the past. I believe many people are aware of concussions and traumatic brain injuries but not how it can affect their brain. Traumatic Brain injuries are a very complex injury with a broad spectrum of symptoms and disabilities. Many healthcare professionals in the field of brain injury often say, “If you’ve seen one concussion, you’ve seen one concussion.” Even a mild

the PNS to control our internal organs and make sure that they work properly. Nerve cells are made up of things called neurons, the cell body of the neuron has a long tinny axon that is covered by something called a myelin sheath, the axons are what pass the information from neuron to neuron and other cells in the body. The axons have a cover to protect them called myelin, this is what allows the brain and spinal cord to communicate with each other (Lindhom, 2014).
