Synapse

1. Neurons are the building blocks of the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal…

release of neurotransmitters. Neurotransmitters are released from synaptic vesicles after they move down the axon and fuse across the cleft. This vesicle transport depends on the protein kinesin which moves synaptic vesicles down the axon to the synapse for release. The inability to move a vesicle down the axon will be kinesin related since kinesin is linked principally with organelles that travel in the anterograde direction on the axon (Nobutaka). The nematode C. elegans is a model…

neural impulse reaches the end of the axon, the neural impulse is now at the terminal button, also known as the axon bulb. The axon bulb contains many neurotransmitters. Neurotransmitters are chemicals that relay messages to another neuron between the synapses, the space between the axon bulb and the dendrites of another neuron. The synaptic gap does not come in contact with one another. The area where the neurotransmitters are released is called the presynaptic gap and the area where the…

How are humans, or any sentient life for that matter, anything more than complex arrangements of meat, neurons, and bone? The biophysical explanation of human physiology explains, quite in depth, the entire genetic makeup and biochemical arrangements from the simplicity of a ball and socket joint to the complexity of the brain. Surely the vast amount of research regarding human physiology could spearhead further research into the complexities of perception and thought, correct? There is no way…

1. Why do you think fast axonal transport is important for synapses? Fast axonal transport is important for synapses because proteins are synthesized in the cell body and are transported down the axon by anterograde to the synaptic terminal. The proteins at the synaptic terminal which have reached the end of their lifetime are then transported back to the cell body by the retrograde transport for degradation and recycling. 2. Can depolarization occur without an action potential being created?…

Learning has the power to transform all of us. We have the opportunity to shape and mold our minds into learning whatever we desire. It wasn’t until my first semester of college that I learned what the six stages of learning are and how our emotions affect our learning. Emotion is the on and off switch for learning. It’s important for us to understand this process and how we learn biologically. Understanding how we learn can be the key to reaching our full potential and being…

more sentimental information such as the recognition of family members. There is not yet a cure for the disease however there are multiple drugs that assist in the inhibiting of acetylcholinesterase, an enzyme which inactivates acetylcholine at the synapse, preventing the normal breakdown of the neurotransmitter. (wisegeek.com) Dopamine Dopamine is neurotransmitter of the brain responsible for the proper usage of a variety of functions including movement, attention, learning, sleep as well as…

even our stomach when to digest food. Neurons communicate with one another through their axon terminals. Axon terminals house synaptic vesicles, which contain neurotransmitter suspended in fluid, that cross the fluid-filled gap that is known as the synapse to reach the receptor sites on the opposite neuron. With it fitting into the receptor sites, neurotransmitters open the ion channels to let sodium rush in and activate the next cell to allow impulse so move from one neuron to the next…

Perry (1999) states that it was originally thought that higher brain functions in the cortex were able to control the lower primitive brain regions and it was this pervasive thought that influenced many therapeutic approaches. In recent years researchers have come to understand that under normal developmental conditions the prefrontal cortex is able to inhibit, organize and modulate the lower brain; however, in children who have experienced trauma the organization is altered. Perry (2012) goes…

(TCO 5) Which of the following is CORRECT concerning REM deprivation? (Points : 5) REM deprivation results in long-term mental illness. REM deprivation only occurs among the elderly. REM deprivation leads to increased amounts of REM sleep on subsequent nights of sleep. REM deprivation can lead to visual impairments. Question 8.8. (TCO 5) The activation-synthesis hypothesis of dreaming states that _____. (Points : 5) the purpose of dreaming is to express…
