Neuron
Neurons as a cell type have very diverse structures. They could be classified by their modalities and morphologies. Their functions are to conduct messages to and from the Central Nervous System and Peripheral Nervous System, or within each system.\ Continue reading Neuron
Hyaline Cartilage
Hyaline means “glass-like” or “transparent” because of how it looks under the microscope. It is the most common cartilage and can be found in locations such as trachea, articular surfaces of bones, larynx and nasal septum. Even though it’s called … Continue reading Hyaline Cartilage
Gastro-esophageal junction
The connection between the lower esophagus and the stomach cardia is known as the gastro-esophageal junction or esophagogastric junction. Histologically this is the transition between the stratified squamous epithelium from the esophagus to the simple columnar epithelium of the stomach. Continue reading Gastro-esophageal junction
Arrector pili
Arrector pili is a small, involuntary muscle composed of smooth muscle cell. It attaches to the hair bulb of the hair follicle and act to pull the hair up during cold or emotional distress, forming the “goose bump” on skin … Continue reading Arrector pili
Fibrocartilage
Fibrocartilage is similar to hyaline cartilage but with the addition of thick and dense collagen fibers that are deposited in the extracellular matrix. It can be found in locations where shock absorption is needed such as intervertebral discs and symphyses … Continue reading Fibrocartilage
Elastic Cartilage
Elastic cartilage is similar to cartilage but with the additional elasticity due to the elastic fibers that are deposited in the extracellular matrix. It can be found in the external ear, external auditory canal, epiglottis and part of the laryngeal … Continue reading Elastic Cartilage
Bone
Bone tissues support and allow body movements. It provides mineral storage of calcium and phosphate, and bone marrow assists in the production of blood cells. It is a tissue composed of cells and the ground substance is mineralized extracellular matrix … Continue reading Bone
Transitional Epithelium
This type of epithelium resembles both stratified squamous and stratified cuboidal as the surface layer could change shape. They are usually found in the urinary tract such as the ureters, urinary bladder and urethra where the organs and tubes need … Continue reading Transitional Epithelium
Simple Columnar Epithelium
Simple columnar epithelium contains cells that are rectangle in shape and have their nuclei arranged on the basal side. Their nuclei also tend to look oval shape. This type of epithelium can be found in the digestive tract, uterine tube … Continue reading Simple Columnar Epithelium
