How to approach histology for Human Anatomy students. Using a key will help get you through it! Add some penguin fairy dust will help too!

Please note: I mis-spoke and said "striated" instead of "stratified epithelium" a couple of times... apologies!

There are lots of histology keys out there, but the one I showed in the video is here: http://www.penguinprof.com/upl....oads/8/4/3/1/8431323

Details:

Tissue in the human body:

Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces.

A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.

Two types of epithelial tissues: (1) Covering & lining epithelia and (2) Glandular Epithelium.

The number of cell layers & the shape of the cells in the top layer can classify epithelium.

Simple Epithelium - one cell layer
Stratified epithelium - two or more cell layers
Pseudostratified Columnar Epithelium - When cells of an epithelial tissue are all anchored to the basement Membrane but not all cells reach the apical surface.
Glandular Epithelium -- (1) Endocrine: Release hormones directly into the blood stream and (2) Exocrine - Secrete into ducts.


Connective: contains many different cell types including: fibroblasts, macrophages, mast cells, and adipocytes. Connective Tissue Matrix is made of two materials: ground substance - proteins and polysaccharides, fiber -- reticular, collagen and elastic.

Classification of Connective Tissue:
Loose Connective - fibers & many cell types in gelatinous matrix, found in skin, & surrounding blood vessels, nerves, and organs.
Dense Connective - Bundles of parallel collagen fibers& fibroblasts, found in tendons& ligaments.
Cartilage - Cartilage is made of collagen & elastin fibers embedded in a matrix glycoprotein & cells called chondrocytes, which was found in small spaces.
Cartilage has three subtypes:
Hyaline cartilage -- Weakest, most abundant type, Found at end of long bones, & structures like the ear and nose,
Elastic cartilage- maintains shape, branching elastic fibers distinguish it from hyaline and
Fibrous Cartilage - Strongest type, has dense collagen & little matrix, found in pelvis, skull & vertebral discs.


Muscle: is divided into 3 categories, skeletal, cardiac and smooth.
Skeletal Muscle -- voluntary, striated, striations perpendicular to the muscle fibers and it is mainly found attached to bones.
Cardiac Muscle -- involuntary, striated, branched and has intercalated discs
Smooth Muscle -- involuntary, nonstriated, spindle shaped and is found in blood vessels & the GI tract.


Nervous: Consists of only two cell types in the central nervous system (CNS) & peripheral nervous system (PNS):
Neurons - Cells that convert stimuli into electrical impulses to the brain, and Neuroglia -- supportive cells.
Neurons -- are made up of cell body, axon and dendrites. There are 3 types of neurons:
Motor Neuron -- carry impulses from CNS to muscles and glands,
Interneuron - interpret input from sensory neurons and end responses to motor neurons
Sensory Neuron -- receive information from environment and transmit to CNS.
Neuroglia -- is made up of astrocytes, oligodendrocytes, ependymal cells and microglia in the CNS, and schwann cells and satellite cells in the PNS.

Snake Venom's TERRIFYING Effect On Human Blood
Snake Venom's TERRIFYING Effect On Human Blood Mohamed Ibrahim 8,363 Views • 3 years ago

Though most snakes aren't venomous, the ones with a deadly bite are so scary that many researchers think humans evolved to naturally fear the sinuous creatures. With good reason. In the video, two men milk the venom of a Russell's viper and then show what happens when one drop of that venom mixes with a glassful of human blood. It's terrifying.

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,561 Views • 3 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

The blood (1 of 3) samer kareem 7,454 Views • 3 years ago

Blood cells travel through the circulatory system suspended in a yellowish fluid called plasma. Plasma is 90% water and contains nutrients, proteins, hormones, and waste products. Whole blood is a mixture of blood cells and plasma.

liver abcess
liver abcess samer kareem 1,710 Views • 3 years ago

Bacterial abscess of the liver is relatively rare; however, it has been described since the time of Hippocrates (400 BCE), with the first published review by Bright appearing in 1936. In 1938, Ochsner's classic review heralded surgical drainage as the definitive therapy; however, despite the more aggressive approach to treatment, the mortality remained at 60-80%.[1] The development of new radiologic techniques, the improvement in microbiologic identification, and the advancement of drainage techniques, as well as improved supportive care, have reduced mortality to 5-30%; yet, the prevalence of liver abscess has remained relatively unchanged. Untreated, this infection remains uniformly fatal. The three major forms of liver abscess, classified by etiology, are as follows: Pyogenic abscess, which is most often polymicrobial, accounts for 80% of hepatic abscess cases in the United States Amebic abscess due to Entamoeba histolytica accounts for 10% of cases [2] Fungal abscess, most often due to Candida species, accounts for fewer than 10% of cases
