you have a heart attack
Nerves can be severed by major bodily trauma. For example, a well-placed bullet wound.
The sympathetic nerves speed up the heart rate, while the parasympathetic nerves slow it down.
I believe the nerves deteriorate.
The finger can be reattached if the veins, arteries and nerves aren't damaged. Rougly 12hours.
If the connection between the vagus nerve and the heart is severed, it can disrupt the normal regulation of heart rate and function. The vagus nerve helps to slow down the heart rate and regulate cardiac activity. Severing this connection can result in an increased heart rate and potential irregularities in heart rhythm.
A heart who's activity is controlled by nerves.
Yes, but not somatic nerves. Instead the heart is enervated by the autonomic nervous system (used mainly to speed up and/or slow down the heart rate). There is also an internal set of nerves (referred to as Perkingi fibers) that are used to synchronize the beats of the heart.
The autonomic nervous system consists of the sympathetic and parasympathetic branches that regulate the heart rate. The sympathetic nerves release neurotransmitters such as norepinephrine to increase heart rate, while the parasympathetic nerves release acetylcholine to decrease heart rate.
Yes, severed nerves in finger tips can be surgically repaired by sewing the nerve endings back together, a procedure known as nerve repair. The success of the surgery depends on various factors, such as the extent of the injury and the timing of the repair. Physical therapy may also be needed to aid in the recovery of nerve function.
