3. The axon terminal is the nerve ending. The nodes speed up the message. The myelin sheath is an insulating membrane. The axon carries impulses away from the cell body. The cell body is the largest part of a typical neuron. The dendrites carry impulses from the environment or from other neurons toward the cell body. The nucleus is the control center of the cell.…
The nerve impulse caused by a charge in the electrical charge across the cell membrane of the axon. When the neuron "fires", this charge…
Nervous impulses are electrical signals that travel along neurons. The electrical signals cannot travel from one neuron to the next directly. The signal crosses the gap, called a synapse, between cells in chemical form. One neuron releases chemicals in response to an action potential (nerve impulse). The chemicals travel across the synapse and stimulate an action potential in the next neuron. These chemicals are known as neurotransmitters. Neurotransmitters are stored in vesicles within a neuron and released through the…
Electrical signals called impulses are carried throughout the nervous system by specialized cells called neurons.…

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.…
When neurones are stimulated they transmit an electrical impulse. Neurones transmit electrical impulses through the polarization inside the membrane of a neurone.…

Budweiser is a reputable brand that has been around for many years. We see it advertised a lot with sporting events. It is a traditional brand that allows for social gatherings of any kind. It allows people to come together and enjoy some beers together. It is easily accessible because it is so well known it is available at almost all stores and bars. Budweiser has established its brand name and image. The consumers who drink Budweiser are loyal to the brand and tradition.…
The electrical impulse (the axon potential) reaches the end of an axon (the axon terminals), they stimulate the release of neurotransmitters. These are chemical messengers that carry a message from the sending neuron across a synapse to receptor sites on a receiving neuron. The sending neuron, in a process called reuptake, then normally reavsorbs the excess neurotransmitter molecules in the synaptic gap. If incoming signals are strong enough, the receiving neuron generates its own action potential and relays the message to other cells.…
Nervous system- Nerve cells within organs of system use electrochemical signals called nerve impulses to communicate with one another and with muscles and glands. Sensory neurons detect changes in and out of body. Nerves carry signals from brain to body.…
2.) On a neuron, the dendtrites receive impulses from other neurons. This information is then passed down to the cell body and on to the axon. Once the information has arrived at the axon, it travels down the length of the axon in the form of an electrical signal known as an action potential. Neurotransmitters are needed to send the information from one neuron to the next. Neurotransmitters are chemical messengers that are released from the axon terminals to cross the synaptic gap and reach the receptor sites of other neurons.…
These electrical impulses are signals that tell out body how to function. When the nervous system is functioning correctly our body easily maintains homeostasis. There are however, many diseases and disorders that can affect the Nervous system, when this happens, effects can vary between very minor systems, and total loss…
The game of basketball is not a game of skill anymore, it is a game of fouls. This is not enjoyable to watch, no one who plays the game knows any of the rules. “When little kids watch basketball on tv it inspires them to play like that in their Youth League, and they take it to a whole other level.” (Bythe,pg.9). Basketball is a team sport. No one wants to play with you if a you're a hog ball, if you’re selfish, or if you try to show off.…
