Dual nerve supply refers to the phenomenon where an organ or structure receives innervation from two different sources, typically from both the sympathetic and parasympathetic divisions of the autonomic nervous system. This arrangement allows for more nuanced regulation of physiological functions, as one division can stimulate activity while the other can inhibit it. For example, the heart receives dual innervation, enabling it to manage heart rate and contractility effectively in response to varying physiological demands.
The sural nerve is cutaneous and therefore does not supply any muscles.
The larynx receives its nerve supply from the vagus nerve (cranial nerve X). Specifically, the recurrent laryngeal nerve innervates the intrinsic muscles of the larynx involved in phonation, while the external branch of the superior laryngeal nerve supplies the cricothyroid muscle.
The nerve supply to the levator scapula muscle is from the dorsal scapular nerve (C5) and the third and fourth cervical nerves (C3, C4) that form the cervical plexus.
what does ninth cranial nerve control? glossopharyngeal nerve is a mixed nerve, it has sensory and motor part. the sensory is at the poserior 1/3 of the tongue. It also is part of the pharyngeal plexus. (9,10,11) The motor part of the nerve ONLY supply the stylopharyngeus muscle!
The nerve supply to muscles is crucial for their function, as it controls muscle contraction and coordination. Motor neurons transmit signals from the central nervous system to muscle fibers, initiating contraction through the release of neurotransmitters at the neuromuscular junction. This connection allows for voluntary and involuntary movements, enabling the body to respond to stimuli and perform various tasks. Disruption in nerve supply can lead to muscle weakness or paralysis.
The trigeminal nerve (cranial nerve V) is considered to have a dual origin as it is both a sensory and motor nerve. It has three main branches that control sensation in the face, as well as muscles involved in chewing.
It should supply with glossopharyngeal & facial nerve.
Facial nerve
what structures does the vagus nerve su
the power supply is tracked by two's.
The sural nerve is cutaneous and therefore does not supply any muscles.
The larynx receives its nerve supply from the vagus nerve (cranial nerve X). Specifically, the recurrent laryngeal nerve innervates the intrinsic muscles of the larynx involved in phonation, while the external branch of the superior laryngeal nerve supplies the cricothyroid muscle.
The nerve supply to the levator scapula muscle is from the dorsal scapular nerve (C5) and the third and fourth cervical nerves (C3, C4) that form the cervical plexus.
