These DSs were first observed at 9 weeks in the distal part of ascending fibers that consist of gracile fasciculus and cerebellospinal-gracile nucleus and white matter of cerebellum. They extend along medulla oblongate to medulla cervix、medulla thorax、medulla lumbalis in accordance with dying-back type degeneration. The corticospinal tract were affected at 18 weeks,and thalamus、the olfactory pathway、the visal pathway、the auditory pathway were affected at 32 weeks.

这种DS从9周龄开始，首先在构成薄束路和脊髓小脑后路的上行纤维的远端区域-薄束核区和小脑白质出现，逐渐按照延髓、颈髓、胸髓、腰髓的顺序，向细胞体方向逆行性地进展。18周龄时波及到锥体路，32周龄时进一步波及到丘脑和嗅觉、视觉、听觉传导路。

Results There was an extensive staining with both P2X2 and P2X4 receptors positive neurons and nerve fibers localized in medulla oblongata. It was mainly localization in the nucleus tractus solitarius,Ⅻ nucleus and ventrolateral medulla of medulla oblongata. It also scattered throughout rest of medulla.

结果 P2X2和P2X4嘌呤受体的阳性神经元和阳性纤维在新生鼠和成年鼠的延髓都有广泛表达，主要分布在孤束核、Ⅻ颅神经核和延髓腹外侧区，延髓其他区域为散在的分布。

Result The medulla exponent of straight guard hair on corsac's back was 81.7%, and that on abdomen was 72.0%, the medulla exponent interval of hairs from 2 parts was 71.4 %-82.9%, indicating the medulla exponent of animals in same family had a certain difference.

结果］沙狐背部直针毛的髓质指数为81.7%，腹部为72.0%，2个部位的髓质指数区间为71.4%~82.9%，说明同科动物的髓质指数存在一定的差异。

medulla：髓质层

称为髓质层(Medulla)是由互相分离的透明多角形的角化细胞所构成. 髓质会随毛发或完全连接、或寸断、或全然没有. 通常在粗发中较易发现. "髓质层"是头发的中心部分,有时会消失或断断续续. 它含有活跃的细胞,有输导养分的功效,

medulla：髓质

角蛋白质的链状结构,使头发具有可伸缩的特性,不易被拉断. 但头发湿的时候较为脆弱,不当牵拉,容易造成损伤. 皮质内,含有具有凝结力和左右头发色质的黑色素. 毛髓质(MEDULLA)位于头发的中心部位,中间是空心的孔状结构,里面含有空气.

medulla：延脑

(1)延脑(medulla) 延脑居于脑的最下部位,与脊髓相连;其主要功能为控制呼吸、心跳、消化等. (2)脑桥(pons) 脑桥位居中脑与延脑之间. 脑桥的白质神经纤维,通到小脑皮质,可将神经冲动自小脑一半球传至另一半球,使之发挥协调身体两侧肌肉活动之功能.

medulla：延髓

1.延髓(medulla)延髓居于脑的最下部,与脊髓相连;其主要功能为控制呼吸、心跳、消化等. 2.脑桥(pons)脑桥位于中脑与延脑之间. 脑桥的白质神经纤维,通到小脑皮质,可将神经冲动自小脑一半球传至另一半球,使之发挥协调身体两侧肌肉活动的功能.

adrenal medulla：肾上腺髓质

肾上腺包括肾上腺皮质(adrenal conetex)和肾上腺髓质(adrenal medulla),二者的形态、结构、胚胎发生、生理作用以及功能的调节都完全不同,是两个独立的内分泌腺.
