ObjectiveThis experiment will seek to demonstrate regulative development in Ambystoma mexicanum embryos. Specifically we will split the morphogenetic field that is responsible for heart formation usin ...
Cyclopamine and jervine teratogens derived from the skunk cabbage Veratrum californicum are known to induce holoprosencephaly in chick embryos when introduced prior to gastrulation. Holoprosencephaly ...
ObjectiveThis experiment attempted to determine the effects of the teratogen cyclopamine on the Shh signaling pathway in axolotl embryos. Groups of axolotl embryos that had undergone gastrulation were ...
PURPOSE: The objective of this experiment is to study the effect of lithium chloride treatment on early blastula xenopus embryos.INTRODUCTION: When the developing embryos of many organisms such as the ...
The development of chick embryos has been studied since Aristotle. It is one of the most intensely studied organisms. One reason for this is that there are great similarities between avian and mammali ...
This experiment allows you to observe the development of a chick embryo outside its shell. Cultured chicks are also more accessible for manipulation. Compare the extent of bone mineralization of contr ...
In order to repeat a published experiment or have someone else repeat yours it is important to use the same materials. For developmental studies that means knowing the precise point in development tha ...
ABSTRACTFibroblast growth factor (FGF) signaling plays a signifigant role in embryonic development. Particularyl FGFs are implicated in mediating epithelial-mesenchymal interactions by means of regula ...
ObjectiveThis experiment explores the ability of the chick chorioallantoic membrane (CAM) to support an excised limb bud from a donor embryo. The chick system will allow observation of general cartila ...
Abstract Choriallantoic membrane (CAM) limb grafting functions as a method to isolate the inductive events of limb formation. Experimenters have the ability to isolate and culture tissues outs ...
The chicken is a classic organism used to illustrate the principles of basic embryology. One of the developmental systems which has been examined in great detail is the circulatory system. In the deve ...
Objective:The purpose of this experiment was to explore the effects of the growth factors bFGF and VEGF on blood vessel formation within the chorioallantoic membrane (CAM) of chick embryos. Background ...
ObjectiveThe purpose of this experiment is to observe the effect of caffeine on the heart rate of three day old chick embryos by directly treating them with five different concentrations of caff ...
Green fluorescent protein (GFP) is responsible for the bioluminescence of the Pacific Northwest jellyfish Aequorea victoria. In A.victoria the 27-kDa protein absorbs blue light from a photoprotein tha ...
More than 22 million American women smoke and approximately 25% of these women continue to smoke during pregnancy (Lambers and Clark 1996). Cigarette smoke has long been associated with increased heal ...

颈部介于头部、胸部和上肢之间。颈部后方以颈椎为界,与项部分隔。颈部由前方的舌骨上、下肌群,外侧的胸锁乳突肌,后方(即颈椎的前方)的椎前肌和斜角肌群围成。颈腔内容纳呼吸道和消化道的颈段及其两侧的大血管、神经和淋巴结等。颈根部还有胸膜顶及肺尖等自胸廓上口突入。这些结构间有疏松结缔组织填充,并于肌肉、器官与血管、神经周围形成筋膜和筋膜间隙。一、境界上界为头部的下界,即下颌骨下缘、下颌角、乳突尖。下界为胸 ...
头由颅和面部两部份组成。颅内包含脑,面部有眼、耳、鼻、舌等特殊感觉器官和呼吸、消化系统的起始部。一、境界与分区头部以下颌骨的下缘、下颌角、乳突、上项线、枕外隆凸与下方的颈部分界。头部以眶上缘、颧弓、外耳门上缘、乳突、上项线和枕外隆凸的连线为界,可分为后上方的颅部和前下方的面部。二、体表标志头部可以扪及若干骨性标志,这些标志均有临床意义:眉弓、颧弓、翼点、乳突、枕外隆凸、上顶线、前囱点(额顶点)、人 ...
【摘要】 神经干细胞(neural stem cells,NSCs)作为具有自我更新及分化为神经元、星形胶质细胞、少突胶质细胞潜能的神经前体细胞,具有广泛的临床应用前景。通过移植可以从结构及功能上修复、改善神经系统疾病。本文就神经干细胞生物学特性,移植治疗的研究现状及在缺血性脑卒中治疗中的应用做出综述。 【关键词】 神经干细胞;移植;缺血性脑卒中 【Abstract ...
