Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell. The space (synapse) between the axon of a motor neuron and a muscle cell is called a neuromuscular junction. The axon of the motor neuron contains synaptic vesicles which contains thousands of molecules of the neurotransmitter acetylcholine. This acetylcholine is released into the space between the axon and the muscle cell. The muscle cell membrane has receptors to accept or to bond with the acetylcholine. This region is called the motor end plate. When the acetylcholine bonds with the protein receptors in the motor end plate, sodium and potassium gates in the region open at the same time

Your mind is comprised of billions of nerve cells (or neurons). Neurons come in all shapes and sizes, however most have three imperative parts: a cell body that contains the core and coordinates the exercises of the neuron; dendrites, short filaments that get messages from different neurons and hand-off them to the cell body; and an axon, a long single fiber that conveys messages from the cell body to dendrites of different neurons.

They have the ability to transmit the signals among the nerve cells. They had known as neurons. Also, communicate the information throughout the body and brain. The brain utilizes neurotransmitters to inform the lungs, heart and stomach to do their functions. Those like, lungs to breath, heart to beat and stomach to digest. In addition, they having the ability to affect the mood, weight, concentration, sleep might cause unfavorable symptoms. While they balanced in the out of range. Neurotransmitter level might be exhausted in several ways. There are two types of neurotransmitters

Sensory nerves transmit sensations such as touch and pain to the spinal cord and from there to the brain,

This means that without really thinking about it, we take immediate action when we are awoken in the middle of the night to the smell of fire/smoke. The nerve pathway contains one group of sensory neurons and two groups of motor neurons with a set of ganglia between them. As you can see in the image below (Figure 2), the ganglia are represented by yellow clusters (see the celiac ganglion, superior mesenteric ganglion, inferior mesenteric ganglion). The red lines represent the preganglionic neurons and as you can see in Figure 2, these motor neurons mostly sit in the central nervous system – see how the red lines stem from the spinal cord. The ganglionic neurons or postganglionic are represented by the blue lines. These motor neurons extend from the ganglia to the organs –see how a “blue” neuron stems from the celiac ganglion to the liver and to the stomach and to the pancreas, for

Homarus americanus have a primitive nervous system, one similar to those of insects. Lobsters lack a brain and only contain about 100,000 neurons, a figure a million times less than the 100 billion found in humans. Ultimately, the American lobster has a bilaterally symmetrical nervous system. There are ganglia on each segment of the body, each made up of a paired hemi-ganglia. The ganglia of neighboring segments are linked by connectives, while the hemi-ganglia are connected by commissures. Overall, the structure of this nervous system appears as a ladder-like chain consisting of a brain, two connectives, and a ventral nerve cord. Because lobsters lack a cerebral cortex, they rely on this complex nervous system to translate pain impulses into the sensation of pain

The nervous system is a compound set of specialized cells and nerves that integrate the voluntary and involuntary actions of the body and send signals between different parts of the body.When it comes to structure, the nervous system has two main parts: the peripheral nervous system and the central nervous system. The peripheral nervous system is made up of ganglia and nerves outside the brain and spinal cord. The central nervous system consists of the spinal cord, nerves and brain.

Explain the organization of neurons into modules in the striate cortex. Specify which neurons respond to color, orientation and

The idea reckons on a fact that the susceptibility of different tissues could act as a contrast. Magnetic susceptibility of different tissues makes them go out of phase with each other thus helping in determining a signal from a particular tissue. SWI is three to six times sensitive than a T2* Gradient Echo MRI. A neuron is the basic unit of a nervous system. It has a cell body which is referred as soma, that comprise of nucleus and ribosomes that helps in protein synthesis. The dendrites are a series of outgrowth branches of the cell body. The axon which is also termed as nerve fiber is a long process that extends from the cell body and carries outgoing signals to its target cells. Axon terminal is the end of a neuron, which is responsible for releasing neurotransmitter into the synapse. A synapse is an environment through which neurons communicate and transmit signals. Axons traverse the white matter while cell bodies are present in the gray matter. A Diffusion Tensor Imaging (DTI) can be used to track motor fiber and thus can help understand if a patient have a white matter track

Basically, afferent neurons receive information and efferent neurons react to the information. In turn, if an efferent neuron is damaged, the muscle will not react. Injury to an afferent neuron disrupts the relay of sensory information. Injury to a cranial nerve results not only in loss of function, but loss of senses as well. One of the most commonly injured cranial nerves, the first cranial nerve, olfactory nerve. Olfactory nerves are what we rely on for our sense of smell (olfaction), also related to the sense of taste. This is the shortest of all the cranial nerves and there are two located on each side of the face. Olfactory nerves consist of multiple nerve roots, approximately two dozen olfactory nerve and afferent nerve fibers. Two of the twelve cranial nerves, the olfactory and optic, originate at the cerebral portion of the brain. CN1 is located in the nasal mucosa of the upper nasal cavity. The nasal area is not protected by the skull deeming this

You’ve more than likely heard someone refer to themselves as being more right-brained and having a more artistic view of the world. Perhaps you have heard someone say they are more intelligent and extremely introverted due to them being left hand dominant. There are a plethora of articles and online quizzes that focus on brain lateralization within humans. But how, if at all, does this affect the furry creatures in our lives, specifically house cats?

* Grooming doesn 't only cover going over their coat with a comb or brush, but also tending to their nails. They will need trimming from time to time and while you are down there, give the pads of their feet a check to see that all is a-okay.

Like any other relationships, be it with our pets or with other people, it is essential that we understand each other for a firm relationship. Each animal has a unique way of expressing itself (Feddersen-Petersen, 2007). Dogs uses a variety of communication signals involving a human’s five basic senses (Wells, 2009). This signals involves their use of vocals and body posture. Oftenly displayed characteristics by a domestic dog is its aggressiveness, submission to owner, playfulness and it also shows fear and anxiety (Feddersen-Petersen, 2007).

In this experiment, a virtual program designed to demonstrate the swimming of a virtual fish, was used. This program is called SWIMMY. SWIMMY was used in this experiment to determine the circuits that are used in the movement of an animal. This is done by presenting the neurons and the neural circuits in a body which can allow and show the movement of the fish’s tail virtually. The movement of the fish tail occurs by the activation of motor neurons. Moore and Stewart, 2007 These two motor neurons can be used to form a circuit that has the ability to generate movement of the fish’s tail in this experiment, however, the neural circuits that will be examined in this experiment are usually used in fish for movement, digestion and respiration, as well as memory and the ability to perceive objects in certain areas.
