What is paracentral posterior disk protrusion at T12-L1 causing pressure over the anterior aspect of the thecal sac?
A paracentral posterior disk protrusion at the T12-L1 level refers to a bulging of the intervertebral disk that is located towards the center and posteriorly, which can encroach upon the spinal canal. This type of protrusion can exert pressure on the anterior aspect of the thecal sac, which houses the spinal cord and nerve roots, potentially leading to symptoms such as pain, numbness, or weakness in the lower extremities. The condition may require monitoring or treatment depending on the severity of symptoms and the degree of nerve compression.

What is paracentral disc protrusion?
Paracentral disc protrusion is a disorder of the spine that causes neck and back pain. An intervertebral disc is swollen or bulging and is putting pressure on the nerve roots when you are diagnosed with this disorder.
What are the different types of nose bleeds and how can they be differentiated from each other?
There are two main types of nosebleeds: anterior and posterior. Anterior nosebleeds occur in the front part of the nose and are more common. They usually result from dry air or minor trauma. Posterior nosebleeds occur in the back part of the nose and are less common but more serious. They can be caused by high blood pressure or a blood clotting disorder. To differentiate between the two, anterior nosebleeds typically involve bleeding from one nostril and are easier to stop, while posterior nosebleeds may involve bleeding from both nostrils and require medical attention.
What helps maintain the intraocular pressure located in the anterior part of the eye?
Intraocular pressure is 16 mm Hg and helps to maintain the shape of the eyeball. Intraocular pressure is maintained by a jelly-like substance, called the vitreous humor, which is located in the posterior cavity of the eye. According to the eyeball's structure it appears in this order: cornea, anterior cavity, pupil, iris, lens, posterior cavity (containing vitreous humor).
What are posterior nosebleeds?
Posterior nosebleeds originate from the back of the nose near the throat and are often more severe and harder to control than anterior nosebleeds which come from the front of the nose. They may be caused by conditions such as high blood pressure, bleeding disorders, or nasal trauma. Immediate medical attention is usually required to stop the bleeding.
Is there a pressure point in your foot?
Yeah there is a pressure point on your wrist, it is between the wrist bone and the tendon farthest away from it.
Focal disc protrusion?
a small protrusion of the disk is caused buy pressure on the spine. speaking to the disk itself if there is a weakened spot in the canula the pressure on that disk is more susceptible to give under the spinal pressure, thus causing it to protrude possibly putting pressure directly on the sciatic nerve.
What is Laser iridotomy?
The purpose of a laser iridotomy is to allow an equalization of pressure between the anterior (front) and posterior (back) chambers of the eye by making a hole in the superior peripheral iris
What area is posterior to the central sulcus?
Postcentral gyrus, or the parietal lobe [Edit: The postcentral gyrus is posterior to the central sulcus, not anterior. The primary motor cortex is located directly anterior to the central sulcus.]
Where is the aqueous humor found?
The aqueous humor is a transparent fluid found in the anterior chamber of the eye, located behind the cornea and in front of the lens. It helps maintain the intraocular pressure and provides nutrients to the cornea and lens.
What is severe pain and constriction around the heart creating a feeling of pressure in the anterior chest?
Angina
What is pathopysiologyof hernia?
hernia develops at place with weakening or absence of muscular covering. it develops when there is an increase in intra-abdominal pressure, causing protrusion of the organs, which can be observed by protrusion of skin. the common sites are: the umbilicus and the inguinal it can also happen internally, in which case, it is called the internal hernia.
What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
