The muscular layer of the stomach is very strong and divided into three layers. The layer is oblique muscle distributing only in the non-glandular part, the strongest of which is in the cardia, forming the cardia sphincter. 答案: 正确答案:inner 点击查看答案 你可能感兴趣的试题 问答题 Glandular...
three muscle layers (circular muscle, longitudinal muscle, and muscularis mucosae). These three muscles can contract and are responsible for some of the many movements of the stomach. The serosa that lies under the longitudinal muscle is the outermost layer that surrounds and encloses the entire...
Yong-Jian Geng, in Vascular Pharmacology, 2022 1 Introduction Smooth muscle is a type of involuntary, non-striated muscle, functionally and morphologically distinct from skeletal muscle and the myocardium. Within the medial layer (tunica media) of blood vessels, smooth muscle cells (SMC) contract ...
Anatomical findings around the sphincter were confirmed in micro-CT images. The sphincter wall comprised three layers: an inner layer of longitudinal bundles, a middle layer of major circular and minor longitudinal bundles, and an outer layer of longitudinal bundles. The stomach outer longitudinal ...
Horner's muscle A thin layer of fibres that originates behind the lacrimal sac from the upper part of the posterior lacrimal crest (a ridge on the lacrimal bone which borders the fossa for the lacrimal sac). The muscle passes outward and forward and divides into two slips surrounding the ...
3. Cardiac Muscle Contracts in Response to Signals from the Cardiac Conduction System The heart wall is composed of three layers. The middle layer, the myocardium, is responsible for the heart’s pumping action. Cardiac muscle, found only in the myocardium, contracts in response to signals from...

reported a localized zone of sonic hedgehog (Shh) signaling that was almost entirely restricted to the adventitial layer of blood vessels in late fetal and perinatal mice (31) (Figure 108.2). Shh protein itself was localized to the adventitia and concentrated close to the border between the ...
