In the white matter area of the medulla oblongata contains ascending and descending nerve tracks which cross the brain and spinal cord. The protrusions in the white matter forms the pyramids with corticospinal nerve connect the cerebrum with spinal cord which controls the movement of voluntary muscles. These nerve tracks cross the left side to the right side of the body. The medulla regulates the force and heart rate through the cardiovascular system and medullary rhythmic area of respiratory center controls the respiratory processes. Other functions are controlling reflexes for vomiting, swallowing, sneezing and coughing and hiccupping.
(iii) Pacemaker- this sends out regular nervous impulses which travel along the axons of the pf the nerve cells out through the walls of the atria. It is located at the top right of the atrium. (iv) Semi-lunar valves- these prevent the backflow of blood into the heart (v) Superior vena cava- this brings deoxygenated blood from the upper part of the body to the heart (vi) Inferior vena cava- brings deoxygenated blood from the lower part of the body to the heart (vii) Pulmonary artery- transports deoxygenated blood away from the right side of the heart to the lungs (viii) Pulmonary vein- this is where oxygenated blood leaves the lungs and returns to the heart (ix) Aorta- passes blood from the left ventricle to the whole body The blood
Later on the field of Science and technology rapidly advanced and Functional endoscopic sinus surgery has revolutionized surgical care and new horizons opened in the management of Sinonasal diseases. Sushruta designed tubular nasal speculum called Netiyantra. Following Sushrutas “Netiyantra” to examine the nose, Pere Dionis described first nasal speculum in 1714. He also tried to explain the origin of nasal polyp by examining nasal polypi. The search to look into the nose and especially into the sinuses continued with Wertheim in 1896 who designed a “conchoscope” to see deeper into the middle meatus.
She had psychological treatment for many times. Her emotional troubles were said to occur due to an bad relationship with her mother and the early loss of her father. She attempted to suicide twice, and for the third and the last time, she committed a suicide in 1963. In her numerous works the traces of her emotional and mental condition can be clearly seen. Sylvia Plath’s work is often self-portraying and really personal; her
I intend to explore one disease of the musculoskeletal system and find out what it is like to live with said disease and found out how much people really know about it. What is anatomy and physiology? Anatomy: The study of the different parts of the body and the relationships between them. Physiology: How each of these parts functions. Composition of bone Bones are made up of many different cells and minerals.
Once the sound waves have rounded the corner of the ear canal, they cause the eardrum to vibrate, stimulating the ossicles of the middle ear (tiny bones called the malleus, incus and stapes – otherwise known as the hammer, anvil and stirrup). These ossicles transmit the sound waves to the cochlea. (Bailey, 2013). The cochlea is a fluid-filled structure in the middle ear. The sound waves are translated to fluid waves in the cochlea that are then sensed by nerves connected to fine hairs that float in the fluid and is then sent on to the brain for interpretation.
Sometimes deep hemorrhages can expand into the ventricles – the fluid filled spaces in the center of the brain. Subdural hemorrhage (SDH): Subdural hemorrhage (SDH) is a collection of blood accumulating in the potential space between the dura and arachnoid mater of the meninges around the brain. Extradural hemorrhage (EDH): An extradural hemorrhage (EDH), also known as an epidural hemorrhage, is bleeding between the inside of the skull and the outer covering of the brain (called the "dura"). Subarachnoid hemorrhage (SAH): Subarachnoid hemorrhage (SAH) is a serious, life-threatening type of stroke caused by bleeding into the space surrounding the
The hip joint is the attachment between the hind limb and the axial skeleton. The pelvis girdle consists of two identical hipbones that ventrally meet at the pelvic symphysis. Dorsally they articulate with the sacrum. Each hipbone consists of the ilium, pubis and ischium that have different ossification centers. In adults, these bones are completely fused and their bodies form the cavity for the articulation with the femur, the acetabulum (8).
Two examples are listed below: a. The Two Fridas: Kahlo explains that this painting was done after her divorce from Diego and the two women resemble different states of the same Frida and Diego’s effect on both. b. The Broken Column: In this painting Kahlo draws half her body with many needles stuck into it and the biggest in her heart. She explains that those needles resemble the different kinds of pain she had to go through and that the biggest was Diego’s.
Interior duodenal stenosis also was found so Duodenoduodenostomy (diamond) was performed with Ladd's procedure after Gastro-jejunostomy (Omega) was made. From 30 to 60% of patients with malrotation or malfixation can have other associated congenital anomalies, either inside or outside the abdominal cavity. In our case the patient was also diagnosed with duodenal stenosis and anal stenosis . Anal stenosis caused her constipation early in life and was fixed with
