called neurons. They communicate by tiny electric movements called synapses that combine in certain patterns to control everything we do: sleep‚ walk‚ think‚ and feel. The synapses happen as a result of outside stimuli. A clear example is when a person gets too close to a candle. Their nervous system sends the stimulus to the brain‚ which tells the finger to back away from the flame. However‚ the synapses wouldn’t happen without neurotransmitters. These are chemicals that flow through neurons‚ which

Nervous System The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. Animals with backbones and spinal columns have a central and a peripheral nervous system. The central nervous system is made up of the brain‚ spinal cord and retina. The peripheral nervous system consists of sensory neurons‚ ganglia and nerves that connect to one another and to the central nervous system. (https://campus.ctuonline

They can influence how vesicles issue neurotransmitters‚ how neurotransmitters are cleaved/reuptake‚ they can hinder receptors‚ destroy receptors‚ and agonistically join to receptors which mimic the neurotransmitter. These are a few. Synapses are vital to the function of the nervous system. The most

Answer: If you have an accident for instance and you damage your head you might have altered sleep habits all the way to coma. Frontal lobe- you might have problem solving difficulties for instance. Parietal lobe- might cause eye hand coordination problems Occipital lobe- might cause defects in vision Temporal lobe- might have problems hearing Brain

motor and inter neurons within the body and these are located on peripheral nerves. All of them work together to collect sensory data and also control the actions of the body. Sensory neurons collect sensory information and convey it to the brain‚ and motor neurons transmit the necessary signals to receptive tissues whilst inter neurons create circuits which creates communication pathways between the central nervous system and the two other neuron types. There are many sub neurons that fall under

atrophy [SMA] is a disorder in which‚ you have a loss of motor neurons. Your muscle symmetry is often off. In addition‚ there is muscle weakness in your spinal cord. This occurs in a hard time sitting up and holding your head up on your own. It is just like when you are a newborn and you need a pillow to sit on the couch. A few major causes of SMA are loss of motor neuron cells or nerve cell. This mutation leads to a deficiency of motor neuron cells or nerve cells. The disorder SMA is tied to the gene

different parts. The video describes the three important jobs our neurons do: receive information from other cells‚ process information‚ and transmit it to the rest of the body. Without our neurons we would have no brain activity. All behavior begins with an action from a neuron. First the brain gathers information from the receptors and spread it around it’s branch fibers‚ or dendrites. Next the information is sent to the soma‚ the neurons cell body‚ where it is combined with other information. Finally

break between the nerve and muscle to activate contraction. The progression in which signals are sent from motor neurons to skeletal muscle fibres to warrant movement of muscles is called neuromuscular junction (Etherington & Hong‚ 2011). Motor neurons‚ Schwann cells‚ muscle fibres and kranocytes are all the different cell types that make up the neuromuscular junction. Motor neurons send out axons to skeletal muscles where an action potential is passed along the axons. The axons form a synaptic
