Help with Histology
Help with Histology DrPhil 108 Views • 3 years ago

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.

Carotid Endarterectomy samer kareem 1,570 Views • 3 years ago

A carotid endarterectomy is performed in a sterile surgical suite or standard operating room. You may go home the same day or stay 1–2 nights after the procedure depending on your medical condition. You receive a local anesthetic or general anesthesia. Your vascular surgeon makes an incision at the front of your neck. After removing the plaque from the artery your vascular surgeon repairs the artery by stitching in a natural graft (formed from a piece of vein from elsewhere in your body) or a woven patch. The incision is closed

Lasik Eye Surgery
Lasik Eye Surgery Mohamed Ibrahim 359 Views • 3 years ago

If you are tired of dealing with glasses or squinting to read signs in the distance, then you should consider LASIK Eye Surgery. In this outpatient refractive procedure, lasers are used to correct vision issues by changing the structure of the cornea. This may entirely eliminate reliance upon glasses or contacts. In this interactive LASIK Eye Surgery, you will assist in numbing the patient’s eye and cleaning the area for the procedure. With a speculum, you will hold the eye open, mark the cornea using a water-soluble ink, then attach a suction ring to it. After that, a specialized blade device is used to cut into the corneal flap and peel it back so that the laser can clear away corneal tissue underneath. This process corrects the shape of the cornea in less than a minute before putting the corneal flap back in place. After the procedure, we will go over LASIK Eye Surgery recovery instructions. Scrub in and let’s get started!
