An example of secretomotor activity can be seen with the lacrimal gland, [1] which secretes the aqueous layer of the tear film. The lacrimal branch of the ophthalmic nerve (itself a branch of trigeminal nerve V1) supplies secretomotor innervation to the lacrimal gland, stimulating its secretion of the aqueous layer.
The injured spinal cord is an “altered” spinal cord. After a SCI, supraspinal and spinal sources of control of movement differ substantially from that which existed prior to the injury, [20] thus resulting in an altered spinal cord. The automaticity of posture and locomotion emerge from the interactions between peripheral nervous system ...
The sympathetic division typically functions in actions requiring quick responses. The parasympathetic division functions with actions that do not require immediate reaction. A mnemonic to summarize the functions of the parasympathetic nervous system is SSLUDD (sexual arousal, salivation, lacrimation, urination, digestion and defecation).
The theory behind the new spinal cord stimulator is that in certain cases of spinal cord injury the spinal nerves between the brain and the legs are still alive, but just dormant. [48] On 1 November 2018 a third distinct research team from the University of Lausanne published similar results with a similar stimulation technique in the journal ...
The SCG provides sympathetic innervation to structures within the head, including the pineal gland, the blood vessels in the cranial muscles and the brain, the choroid plexus, the eyes, the lacrimal glands, the carotid body, the salivary glands, and thyroid gland. [6] The postganglionic axons of the SCG form the internal carotid plexus.
Injury to the chorda tympani nerve leads to loss or distortion of taste from anterior 2/3 of tongue. [13] However, taste from the posterior 1/3 of tongue (supplied by the glossopharyngeal nerve) remains intact. The chorda tympani appears to exert a particularly strong inhibitory influence on other taste nerves, as well as on pain fibers in the ...
The subject was a 37-year-old male who suffered an injury to the cervical spinal cord 17 years prior. After initial total paralysis below the neck, the subject eventually regained some movement of the arms and fingers and limited movement in the lower limbs.
The four main divisions of the spinal column, from top to bottom: cervical, thoracic, lumbar, and sacral. The lateral grey column (lateral column, lateral cornu, lateral horn of spinal cord, intermediolateral column) is one of the three grey columns of the spinal cord (which give the shape of a butterfly); the others being the anterior and posterior grey columns.
