  • 후두근의 운동지배신경에 관하여 일반적으로 알려진 사실은 윤상갑상근이 상후두신경의 의지에 의하여 지배되는 것 외에는 모든 후두내근이 반회후두신경에 의하여 지배된다는 것이다. 이중에서 갑상피열근이나 피열근에 대하여 상후두신경과 반회후두신경의 이중지배(dual supply)는 오랜동안 논란이 되어왔다. 특히 피열근에 분포하는 신경은 반회후두신경의 피열분지에 의하여 지배되며 또한 상후두신경의 내지의 일부인 ramus porforantes에 의해서도 이중지배를 받는다고 알려져 왔다. 그러나 한편 이러한 피열근의 운동신경지배 중 상후두신경의 역할에 대해서 적지 않은 보고가 후두의 신경해부학적인 고찰 및 전기적 자극을 통한 연구에서 단지 피열근 근처에서 twig을 형성할 뿐, 직접적인 운동지배 현상은 보이지 않음을 입증하여 피열근은 오직 반회후두신경에 의하여 운동지배된다고 주장하였다.

  • In order to investigate the effect of aconitine upon the parasympathetic innervation, the isolated rabbit duodenal preparation pretreated with atropine and tetrodotoxin were observed. The results obtained in this work were summerized as follows: 1. The excitatory response was evoked by the administration of aconitine ($100{\mu}g/ml$). 2. The contraction was blocked by the pretreatment with atropine ($10{\mu}g/ml$). 3. The contraction was completely blocked by the pretreatment with tetrodotoxin($10{\mu}g/ml$). These experimental evidences indicate that the excitatory response by aconitine is due to the parasympathetic nerves.

  • The perineum is comprised of diverse anatomic structures with mixed sympathetic and somatic innervation. The coccyx is innervated by the coccygeal nerves and branches of the fifth sacral root. Recently, ganglion impar block has been introduced as an alternative means of managing intractable pain of sympathetic origin, coccygodynia by trauma, tenesmus and perineal hyperhydrosis. We managed a 59-year-old female patient who had suffered from perineal pain by metastasis of cervical cancer. Approach to impar ganglion through the anococcygeal ligament was impossible because her coccyx was hyperflexed anteriorly by old fracture. But we could perform ganglion impar block successfully by approach through the separation of sacrum and coccyx.

  • The Horner's syndrome includes anisocoria as a result of miosis of the involved pupil with ptosis of the upper and lower lids, which results in slight narrowing of the palpebral fissure. Ipsilateral facial hyperemia and anhidrosis over the face and neck are less common features. The findings with Horner's syndrome are a result of the loss of sympathetic innervation to the ipsilateral eye and face. Recently we experienced 3 cases of Horner's syndrome that developed postoperatively and report briefly with literature.

  • Herpes zoster virus (HZV) infections are caused by reactivation of the varicella zoster virus. Reactivation symptoms commonly affect the thoracolumbar trunk, and rarely affect the mandibular branches of the trigeminal nerve. When the mandibular branches are involved, lesions appear proximal to the innervation area. This condition may be associated with exfoliation of the teeth and osteonecrosis of the jawbone. We report a case of mandibular osteomyelitis after herpes zoster infection and we present a review of the literature on mandibular-branch involvement of HZV-related osteonecrosis.

  • Blepharoptosis is the state that upper eyelid sagges, palpebal fissure becomes narrow due to disorder of a levator palpebrae superioris or innervation. It affects not only the physical vision but also mental shrink. In the view of oriental medicine, there are various causes, among them mainly cause is the deficiency of spleen Gi. The other hand, we treated a patient who suffered from blepharoptosis(with headache, exotropia, dizziness) differentiate from stagnation of Gi(energy) and blood stasis with Sungihwalhyeoltang(順氣活血湯) mostly. After about 40days of Sungihwalhyeoltang(順氣活血湯) centered treatment, acupunture, we observed an improvement Based on this experience, it is considered that stagnation of Gi(energy) and blood stasis can bring about blepharoptosis.

  • Neurogenic inflammation has been recognized to play an important role in initiating and sustaining of pulp inflammation. The pulpal innervation may modulate several aspects of the inflammatory response via secretion of neuropeptides. In this present study, these neuropeptides that may be questioned about roles in recruiting leukocytes by inducing the release of the chemokine IL-8 in the pulp during inflammation were tested. The response of human pulp cells in releasing IL-8 after the stimulation with SP and/or CGRP were investigated.(omitted)

  • Anatomical variations of the sternocleidomastoid muscle (SCM) have been observed to occupy multiple origins and insertion points and have supernumerary heads, sometimes varying in thickness. During routine dissection, a SCM was observed to have six distinct insertions that interface with the course of the superior nuchal line, ending at the midline, bilaterally. This variation was also seen to receive innervation from the accessory nerve as well as the great auricular nerve. To our knowledge, this variant of supernumerary insertions and nerve innervations has not yet been reported. These variants may pose as problematic during surgical approaches to the upper neck and occiput, and should thus be appreciated by the clinician. Herein we discuss the case report, possible embryological origins, and the clinical significance of the observed variant SCM.

  • Transsexual individuals with gender dysphoria or gender identity disorder are rare, with a prevalence reported to range from 0.002% to 0.014%. Studies have shown that mastectomy yields significant improvements in body image and self-esteem in female-to-male transsexual patients. In patients with grade III breast ptosis, mastectomy with a nipple-areolar complex (NAC) graft is the most commonly used technique, although it has several disadvantages. In the case described herein, a bilateral mastectomy preserving the NAC in an inferior pedicle was performed. Additionally, a thin superior thoracic dermal-fat flap was preserved and eventually sutured at the previous inframammary fold, preventing an inverted T scar. This case shows the advantage of this technique for preserving the blood supply and innervation of the NAC, with a low hypopigmentation risk. Furthermore, in this technique, the patch effect does not impair the results of the NAC graft, and there is no need to use an inverted T scar that may result in thoracic feminization.

  • Both brown and white adipose tissues (BAT/WAT) are innervated by the peripheral nervous system, including efferent sympathetic nerves that communicate from the brain/central nervous system out to the tissue, and afferent sensory nerves that communicate from the tissue back to the brain and locally release neuropeptides to the tissue upon stimulation. This bidirectional neural communication is important for energy balance and metabolic control, as well as maintaining adipose tissue health through processes like browning (development of metabolically healthy brown adipocytes in WAT), thermogenesis, lipolysis, and adipogenesis. Decades of sensory nerve denervation studies have demonstrated the particular importance of adipose sensory nerves for brown adipose tissue and WAT functions, but far less is known about the tissue's sensory innervation compared to the better-studied sympathetic nerves and their neurotransmitter norepinephrine. In this review, we cover what is known and not yet known about sensory nerve activities in adipose, focusing on their effector neuropeptide actions in the tissue.
