Hemorrhoids are classified into two general categories: internal and external. Internal hemorrhoids lie far enough inside the rectum that you can't see or feel them. They don't usually hurt because there are few pain-sensing nerves in the rectum. Bleeding may be the only sign that they are there. Sometimes internal hemorrhoids prolapse, or enlarge and protrude outside the anal sphincter.
Cerebrospinal fluid (CSF) collection is a test to look at the fluid that surrounds the brain and spinal cord. CSF acts as a cushion, protecting the brain and spine from injury. The fluid is normally clear. The test is also used to measure pressure in the spinal fluid. See also: CSF culture.
The Meaning of Anam Cara. Anam Cara refers to the Celtic spiritual belief of souls connecting and bonding. In Celtic Spiritual tradition, it is believed that the soul radiates all about the physical body, what some refer to as an aura. When you connect with another person and become completely open and trusting with that individual, your two souls begin to flow together.
