Radiology

Radiology is a branch of medicine that uses imaging technology to diagnose and treat disease. Radiology may be divided into two different areas, diagnostic radiology and interventional radiology.
X-Ray

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation.
USG (Ultrasonogram)

An ultrasound is an imaging test that uses sound waves to make pictures of organs, tissues, and other structures inside your body. It allows your health care provider to see into your body without surgery. Ultrasound is also called ultrasonography or sonography.
CT Scan

The term “computed tomography,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images, or “slices.” These slices are called tomographic images and can give a clinician more detailed information than conventional x-rays. Once a number of successive slices are collected by the machine’s computer, they can be digitally “stacked” together to form a three-dimensional (3D) image of the patient that allows for easier identification of basic structures as well as possible tumors or abnormalities.
MRI

Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.

No.	Cranial Nerves	Functions
I	Olfactory Nerve	Smell
II	Optic Nerve	Vision
III	Oculomotor Nerve	Eye movement, pupil constriction
IV	Trochlear Nerve	Eye movement
V	Trigeminal Nerve	Somatosensory information (touch, pain) from the face and head, muscles for chewing.
VI	Abducens Nerve	Eye movement
VII	Facial Nerve	Taste (anterior 2/3 of tongue), somatosensory information from ear, controls muscles used in facial expression.
VIII	Vestibulocochlear Nerve	Hearing, balance
IX	Glossopharyngeal Nerve	Taste (posterior 1/3 of tongue), Somatosensory information from tongue, tonsil, pharynx, controls some muscles used in swallowing.
X	Vagus Nerve	Sensory, motor and autonomic functions of viscera (glands, digestion, heart rate)
XI	Spinal Accessory Nerve	Controls muscles used in head movement.
XII	Hypoglossal Nerve	Controls muscles of tongue

Stoneman Syndrome

SelvaJuly 23, 2021Anatomy, Bone, disorders, Syndrome No comments

Stoneman syndrome or fibrodysplastic ossificans progressiva (FOP) or Munchmeyer's disease is a rare genetic disease of ectopic soft tissue calcification with hand and foot deformities leading to severe restriction of joint movements. It was first described in 1692 in a young patient who turned into wood. It may be sporadic or autosomal dominant. The disease is caused by mutation in the bone morphogenic protein (BMP) type I (Activin A receptor, type I [ACVR1]) leading to dysregulated bone formation.The incidence, as reported from Europe and United States, is around 1 in two million individuals.
