Are salivary glands endocrine or exocrine glands? The sero-mucous glands are also visible in this slide. Refer to the slides in the Cardiovascular Tissue Slides folder as you complete this worksheet. Nervous tissue is composed of nerve cells neurons and a variety of support cells.
The individual exocrine secretory unit, or acinus, is formed by a group of pyramidal-shaped pancreatic acinar cells clustered around a central lumen into which they secrete their products. In the secretory phase, the endometrium and its glands and blood vessels are fully expanded. The filtrate then flows into the urinary space that is directly continuous with the first segment of the renal tubule, the PCT.
The cytoplasmic striations represent the same organization of myofilaments sarcomeres and alignment of sarcomeres as in skeletal muscle, and the mechanism of contraction is the same.
From the PhysioEx main menu, select Histology Tutorial. At the Histology review supplement time salivary gland secretions moisten the food and begin to hydrolyze carbohydrates. In the respiratory bronchiole, the epithelium becomes simple cuboidal and the continuous smooth muscle layer is interrupted at intervals by the presence of alveoli inserted into the bronchiolar wall.
The kidney also plays an endocrine role in secreting compounds that increase blood pressure and stimulate red blood cell production. The cases of the skeletal muscle tissue of the pharynx and diaphragm are more complex.
Why is the thyroid gland considered to be an endocrine organ? Skeletal muscle also has an extensive connective tissue component that, in addition to conducting blood vessels and nerves, becomes continuous with the connective tissue of its tendon.
The middle, myometrial layer of the uterine wall is composed of several layers of smooth muscle oriented in different planes. When the screen comes up, click Select an Image Group.

That was the main thing which helped me in understanding the ways we study and interpret histological organization and details.
My name is Sarah Bellham, and I will be your hostess on this exciting histology adventure. In the loop of Henle, lining cells are simple squamous to simple cuboidal. Traditional medical training programs will find the content at Histology-World useful as a supplement for their histology class as well.
Four major layers are apparent when the wall of the esophagus is cut in transverse section: If you know of other great websites, please let me know. As an individual oocyte grows, granulosa cells proliferate from a single layer of cuboidal cells that surround the oocyte to a multicellular layer that defines a fluid-filled spherical follicle.
The smallest distal branches of the renal artery become the afferent arterioles that directly supply the capillaries of the glomerulus. What are the primary functions of the respiratory epithelium? Because thin-walled veins conduct blood back to the heart against gravity, valves not present in arteries also are present at intervals to prevent backflow.
Generally, a single axon arises from the cell body at a pale-staining region axon hillockdevoid of Nissl bodies. The central lumen is the direct connection to the duct system that conveys the exocrine secretions out of the gland. Here we can see the abrupt change in epithelium at the gastroesophageal junction, where the esophagus becomes continuous with the stomach.
It consists of two components: Extrinsic innervation only modulates the inherent activity. The pale-staining parafollicular cells secrete the protein hormone calcitonin. Processes of adjacent podocytes interdigitate with one another, leaving only small slits filtration slits between the processes through which fluid from the blood is filtered.
