Emergency Intraosseous Infusion
Emergency Intraosseous Infusion samer kareem 3,570 Views • 3 years ago

For patients in extremis from respiratory failure or shock, securing vascular access is crucial, along with establishing an airway and ensuring adequacy of breathing and ventilation. Peripheral intravenous catheter insertion is often difficult, if not impossible, in infants and young children with circulatory collapse. Intraosseous (IO) needle placement, shown in the images below, provides a route for administering fluid, blood, and medication. An IO line is as efficient as an intravenous route and can be inserted quickly, even in the most poorly perfused patients.

Help with Histology

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.

What is Major Depressive Disorder?
What is Major Depressive Disorder? samer kareem 2,137 Views • 3 years ago

Possible causes include a combination of biological, psychological, and social sources of distress. Increasingly, research suggests these factors may cause changes in brain function, including altered activity of certain neural circuits in the brain. The persistent feeling of sadness or loss of interest that characterizes major depression can lead to a range of behavioral and physical symptoms. These may include changes in sleep, appetite, energy level, concentration, daily behavior, or self-esteem. Depression can also be associated with thoughts of suicide. The mainstay of treatment is usually medication, talk therapy, or a combination of the two. Increasingly, research suggests these treatments may normalize brain changes associated with depression.

Carotid Endarterectomy samer kareem 1,608 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

Norepinephrine
Norepinephrine samer kareem 1,877 Views • 3 years ago

Norepinephrine is synthesized from dopamine by dopamine β-hydroxylase.[7] It is released from the adrenal medulla into the blood as a hormone, and is also a neurotransmitter in the central nervous system and sympathetic nervous system where it is released from noradrenergic neurons.

Anatomy of uterus and adnexa
Anatomy of uterus and adnexa samer kareem 17,790 Views • 3 years ago

The most common position of the uterus is anteverted (cervix angles forward) and anteflexed (body is flexed forward). The position of the uterus in the adult is liable to considerable variation, depending chiefly on the condition of the bladder and rectum. Adnexa: In gynecology, the appendages of the uterus, namely the ovaries, the Fallopian tubes, and the ligaments that hold the uterus in place.
