Smooth muscle number of nuclei.

VIDEO ANSWER:Hello students. Let us solve this question in this question we have to differentiate between skeletal muscle, smooth muscle and cardiac muscles. O…Smooth Muscle. Smooth muscle is made up of cells that contain a single central nucleus. The cells stick together and are connected by specialised cell junctions, called gap junctions. The cells are spindle shaped, and the nucleus is central. This diagram shows a few of the cells that can be seen in the stained section below.The vagal nucleus consists of four nuclei located in the medulla oblongata. The three main nuclei are the dorsal motor nucleus of the vagus nerve (cranial nerve [CN] X), nucleus ambiguus, and the solitary nucleus. The fourth nucleus has a minor input from the vagus nerve, the spinal trigeminal nucleus, which receives the main input from the trigeminal nerve. These nuclei all contribute to the ...Smooth muscle tumors are here considered an essentially dichotomous group composed of benign leiomyomas and malignant leiomyosarcomas. ...

Cardiac muscle fibers are long, branched cells, shaped like cylinders joined end-to-end, with one or two nuclei located centrally. The fibers are separated by collagenous tissue that supports the capillary network of cardiac tissue. The myofilaments of cardiac muscle are arranged in a similar pattern to skeletal muscle, resulting in cross ...In mammals, a ring of smooth muscle lies close to the pupillary edge of the iris.
