In which division of the nervous system would nerve regeneration be unlikely to occur?
In the central nervous system (CNS), which includes the brain and spinal cord, nerve regeneration is unlikely to occur due to limited regenerative capacity and the presence of inhibitory factors that hinder nerve growth. Conversely, in the peripheral nervous system (PNS), nerve regeneration is more possible, as peripheral nerves have a greater ability to regenerate under certain conditions.
Neurons that carry impulses away from the central nervous system?
Neurons that carry impulses away from the central nervous system are called motor neurons. They transmit signals from the brain and spinal cord to muscles or glands, allowing for voluntary and involuntary movements to occur.
In which of these places does peristalsis not occur?
Peristalsis does not occur in the central nervous system. It is responsible for the wave-like muscle contractions that move food through the digestive system, but it is not involved in neural signaling in the brain or spinal cord.
What is the Common route of central nervous system invasion by pathogens is through?
The common route of central nervous system invasion by pathogens is through hematogenous spread, in which the pathogens enter the bloodstream and are carried to the brain or spinal cord. This can occur following infections in other parts of the body, such as respiratory or urinary tract infections.
Are reflexes mediated via the central nervous system or the peripheral nervous system or both?
Usually when we talk about reflexes -we are referring to two things: primary sensory processing (peripheral nervous system) followed by a motor response (central nervous system). These types of reflexes do not require higher-order cognitive function to occur - but the brain is made aware of what is going on, presumably so that we learn to avoid the harmful stimulus in the future. For example, the accidental placement of a hand on a hot surface would usually result in an immediate withdrawal reflex. What's happening here is that pain receptors in the skin - in this case 'nociceptors' activated by thermal stimuli - send impulses to neurons in the spinal cord (the spinal cord is part of the central nervous system) that share circuits with neurons that control muscle contractions. These in turn fire, resulting in an immediate flexion (movement toward the body) of the affected limb.
What two Critical symptoms may occur when a patient takes an overdose of central nervous system depressants?

What nervous system?
The nervous sysytem is the control unit of the body.It is responsible for regulating and coordinating the activities of all the other sysytem of the body.Through the nervous systemthe body is able to adjust to changes that occur within itself and in its surroundings. It is divided into 2 principal systems: -The Central Nervous System -Peripheral Nervous System

When do blackouts occur after taking alcohol?
Alcohol is a depressant of the central nervous system; it has a tendency to partially or completely shut down the normal functions of the brain.

The common route of central nervous system invasion by pathogens is through hematogenous spread, in which the pathogens enter the bloodstream and are carried to the brain or spinal cord. This can occur following infections in other parts of the body, such as respiratory or urinary tract infections.
When can the symptoms of mitochondrial myopathies first appear?
These disorders can occur in infancy, childhood, or adulthood. In general, individuals with mitochondria dysfunction have abnormalities in the central nervous system

What is transmission chemistry?
Transmission chemistry refers to the study of chemical processes that occur during the transmission of signals in the nervous system. This includes the release and reception of neurotransmitters at synaptic connections between neurons, which are essential for communication within the brain and body. Understanding transmission chemistry is crucial for unraveling how the nervous system functions and identifying potential targets for therapeutic interventions in conditions such as neurodegenerative diseases and mental health disorders.
What is a somatic reflex and how does it occur through the CNS?
A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.
Why complete recovery from injuries to the nervous system unusually does not occur?
the injury is gay
