Nerves

I wouldn't use the word "occur" since a synapse is a structure, not an event, but yes, it is located between nerve cells, or more specifically, it is where the dendrites of two nerve cells meet.

no a nerve cannot tear but they can burst.

The characteristic that demonstrates the vast ability of our brain and nerves to communicate large amounts of information is neuroplasticity. This refers to the brain's ability to reorganize itself by forming new neural connections throughout life, allowing it to adapt to new experiences, learn, and recover from injury. Additionally, the intricate network of neurons and synapses enables rapid transmission of signals, facilitating complex behaviors and interactions. This combination allows for the sophisticated processing and integration of information essential for advanced cognitive functions.

Best Answer: They make chemicals that are gas-like. Neurotransmitters.

Neuron cells, or neurons, play a crucial role in transmitting signals throughout the nervous system, enabling communication between the brain and the body. Dysfunction or damage to neurons can lead to a range of neurological disorders, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Additionally, the loss of neuron function can result in impaired motor skills, cognitive deficits, and altered sensory perceptions. Ultimately, healthy neuron cells are essential for maintaining overall neurological health and functioning.

Leaping across synapse refers to the process of neurotransmission, where chemical signals (neurotransmitters) are released from one neuron and cross the synaptic gap to bind to receptors on a neighboring neuron. This process allows for communication between neurons, enabling the transmission of signals throughout the nervous system. The term emphasizes the dynamic and rapid nature of this signaling, which is essential for various brain functions, including learning and memory.

The length of a neuron can vary significantly depending on its type and location in the body. For instance, motor neurons that extend from the spinal cord to the toes can be over a meter long, while interneurons in the brain may only be a fraction of a millimeter. Generally, neurons are one of the longest cells in the body, with some axons stretching over long distances to transmit signals efficiently.

Yes, the transmission of information between neurons involves chemicals known as neurotransmitters. When an electrical impulse reaches the end of a neuron, it triggers the release of these neurotransmitters into the synaptic cleft, the gap between neurons. The neurotransmitters then bind to receptors on the adjacent neuron, facilitating the continuation of the signal. This chemical signaling is crucial for communication within the nervous system.

A chemical synapse is a specialized junction that allows communication between neurons or between a neuron and another type of cell, such as a muscle cell. It involves the release of neurotransmitters from the presynaptic neuron, which diffuse across the synaptic cleft and bind to receptors on the postsynaptic cell, triggering a response. This process is crucial for the transmission of signals in the nervous system, enabling a wide range of physiological functions. Unlike electrical synapses, chemical synapses allow for more complex and modulated signaling.

Repolarization of a neuron is primarily caused by the efflux of potassium ions (K+) out of the cell through voltage-gated potassium channels. After an action potential, these channels open, allowing K+ to flow out, which helps restore the negative membrane potential. This process is essential for returning the neuron to its resting state, preparing it for the next action potential. Additionally, the inactivation of sodium channels also contributes to this phase of the action potential.

A neuron is best described as a specialized cell in the nervous system that transmits electrical and chemical signals. It consists of a cell body, dendrites that receive signals, and an axon that sends signals to other neurons or muscles. Neurons play a crucial role in processing and communicating information throughout the body, enabling functions such as movement, sensation, and cognition.

At the start of a nerve impulse, also known as an action potential, there is a rapid change in the ionic composition of the neuron. Sodium (Na+) channels open, allowing Na+ ions to flow into the cell, which depolarizes the membrane and shifts the internal charge from negative to positive. This depolarization is followed by the opening of potassium (K+) channels, allowing K+ to exit the cell, which eventually helps to repolarize the membrane. The coordinated movement of these ions is crucial for the propagation of the nerve impulse along the neuron.

Chemical-gated channels, also known as ligand-gated channels, are primarily found in the dendrites and the cell body (soma) of a neuron. These channels open in response to the binding of neurotransmitters, allowing ions to flow into or out of the neuron, which can lead to depolarization and the generation of an action potential if the threshold is reached. This mechanism is crucial for synaptic transmission and the integration of signals.

The bone that protects the eye are the facial bone. It's function is for you to be able to see.

Motor neurons play a crucial role in the reflex arc by transmitting signals from the spinal cord to the muscles. When a sensory neuron detects a stimulus, it sends a signal to the spinal cord, where interneurons process the information and activate the motor neurons. This leads to an immediate response, such as muscle contraction, allowing for a quick reaction to stimuli without the need for conscious thought. Thus, motor neurons are essential for executing the reflex action in response to external stimuli.

Acetylcholine is degraded in the synapse primarily by the enzyme acetylcholinesterase. This enzyme hydrolyzes acetylcholine into acetate and choline, preventing its accumulation and ensuring rapid termination of the neurotransmitter's action. By breaking down acetylcholine, acetylcholinesterase helps maintain proper signaling between neurons and muscle cells, allowing for precise control of muscle contraction and other physiological processes.

ooh, you're in trouble dude! see a doctor, you may probably have to get a shot to get rid of it. Maybe a urinary tract infection. My mom used to make me drink pure cranberry juice for a day or two to make it go away.

hi all denervation hypersenstivity means... the remaining spinal exictatory ending release mediators that cause hypersensitivity.. as a compansatory mechanism to compnsate the lesion occurs.. this leads to sprouting of collaterals from existing neurons with formation of additional exitatory endings on inter neurons and motor neurons.. and that what explains return of reflexs and some activity after the end of spinal shock post to lesion whether its UMNL or LMNL. and its the base of rehabilitaion and control of the unvolntry movement and spasticty developed below the level of lesion due to dessuction of the desinding signals.. physical therapy... work in rehabiltaion programs for neurological disorder.

Dendrites are the multi-branched projections off the nerve cell body.

Place finger pressure on the proximal and distal branches of the nerve where then run under the medial side of the heel (about 2/3rds of the way from the back of the heel and at the beginning of the inner longitudinal arch). It will be extremely painful to palpate these areas.
