Nerves

The space between two neurons where communication occurs using chemical messages is called the synaptic cleft. Neurotransmitters are released from the axon terminal of the sending neuron and bind to receptors on the dendrites of the receiving neuron, facilitating the transmission of signals between the two.

Microglia are the glial cells that monitor the health of neurons and can transform into a special type of macrophage to protect endangered neurons.

Once you have the action potential made from the influx of Na traveling down the axon depolarizing it. The action potential reaches the axon terminals, the depolarization causes Ca2+ to enter the cell and that causes the release of the neurotransmitters out of the axon terminals and into the dendrites of the next axon to continue the signaling pathway.

The sodium-potassium pump is mainly responsible for establishing and maintaining the resting potential of a neuron. It actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients, contributing to the overall negative membrane potential.

The structure responsible for nourishing and maintaining the entire neuron is called the glial cells, specifically astrocytes. Astrocytes provide support for neurons by regulating the surrounding environment, supplying nutrients, and helping with neurotransmitter recycling. They also play a role in repairing damage to neurons and forming the blood-brain barrier.

The release of 'neurotransmitter substances' from an axon's perifery which traverse the synaptic cleft - the space between axon and adjoining dendrite - to both affect and effect the adjoining dendritic "perifery" which then re-initiates signal propagation to the next bunch of exonic nerve "endings".

There are few specific treatments for motor neuron diseases, and efforts focus on reducing the symptoms of muscle spasm and pain while maintaining the highest practical level of overall health

Some of the better known motor neuron diseases include amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, spinal muscular atrophy (SMA), and primary lateral sclerosis (PLS). These diseases affect the motor neurons in the brain and spinal cord, leading to muscle weakness, atrophy, and impaired movement.

Motor neuron diseases are a group of neurological conditions that affect the nerve cells responsible for controlling voluntary muscle movements. Examples include amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy. These diseases can lead to muscle weakness, atrophy, and eventually loss of motor function.

Muscles of the legs are most often affected, leading to clumsiness, unstable gait, or lower limb paralysis. Muscle cramps and fasciculations (twitching) occur with most motor neuron diseases. Facial muscles may also be affected

A synaspe.. something like that lol

Yes, nerve conduction requires ATP to function. ATP provides the energy necessary for the transport of ions across the cell membrane, which is essential for generating and propagating action potentials along the nerve fibers.

The three classes of neurons are sensory neurons, motor neurons, and interneurons. Sensory neurons transmit sensory information from sensory organs to the central nervous system (CNS), motor neurons carry signals from the CNS to muscles and glands to control movements, and interneurons facilitate communication between sensory and motor neurons within the CNS.

The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.

Nerves do not fire at varying intensities; for example, neurons won't fire at a stronger intensity if you're hit with a baseball in comparison to a marble. The difference between the two stimuli is the number of firing neurons. After being hit with a baseball, the affected neurons will fire more frequently than if hit with a marble.

Nothing stays the same, right? The answer is, of course.

The long branch of a nerve cell is called an axon. It transmits electrical signals away from the cell body to communicate with other neurons or muscles. The axon is covered in myelin, which helps to speed up signal transmission.

Nerve cells are difficult to see because they are often very thin and have complex structures that are densely packed in the brain and nervous system. Additionally, nerve cells do not readily stain with conventional laboratory techniques, making them hard to visualize under a microscope.

Nerve cells can be killed by various factors, including physical trauma, lack of oxygen, toxins, infections, autoimmune responses, and genetic disorders. Additionally, conditions such as stroke, neurodegenerative diseases (e.g., Alzheimer's, Parkinson's), and certain medications can also damage or kill nerve cells.

When a neurotransmitter lands on their receptor site, they can either excite of inhibit the receiving cell. To excite a cell, positive sodium ions flow to it, which depolarizes the membrane in a similar way to a nerve impulse. The depolarizing effect spreads through the membrane and only last for 1/3 of a millisecond.

A synapse is a structure that allows communication between neurons. Information is transmitted across the synapse through the release of neurotransmitters from the presynaptic neuron, which then bind to receptors on the postsynaptic neuron, leading to changes in the postsynaptic neuron's electrical activity.

The three main types of audits are financial audits, operational audits, and compliance audits. Financial audits focus on financial statements and records to ensure accuracy and compliance with regulations. Operational audits assess efficiency and effectiveness of processes and procedures. Compliance audits verify adherence to laws and regulations.

Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form interconnected circuits within the central nervous system. They are thus crucial to the biological computations that underlie perception and thought. They provide the means through which the nervous system connects to and controls the other systems of the body, for example the specialized synapse between a motor neuron and a muscle cell is called a neuromuscular junction. The adult human brain has been estimated to contain from 1014 to 5 × 1014 (100-500 trillion) synapses.[citation needed] The word "synapse" comes from "synaptein", which Sir Charles Scott Sherrington and colleagues coined from the Greek "syn-" ("together") and "haptein" ("to clasp"). Chemical synapses are not the only type of biological synapse: electrical and immunological synapses exist as well. Without a qualifier, however, "synapse" commonly refers to a chemical synapse.

Yes, dendrites are extensions of nerve cells that receive signals from other nerve cells. Sensory neurons, which carry sensory information from the peripheral nervous system to the central nervous system, have dendrites that receive stimuli from the environment and transmit them as electrical impulses to the cell body.

When the action potential (electrochemical signal) reaches the end of the nerve, calcium channels open, causing synaptic vesicles containing neurotransmitters to bind with the neuronal membrane. When this happens, the neurotransmitters are released into the synaptic cleft (process is called exocytosis). Once in the synaptic cleft, they can bind with postsynaptic neuron or muscle cell receptors.
