1. Anus
The posterior opening of the digestive tract.

2. Bacillus
A class of bacteria which are rod-shaped. Belonging to this class are: E. coli , Salmonella , Shigella, Klebsiella , Enterobacter , Clostridia; of these, Bacillus Calmett-Gu rin is administered for vaccination against tuberculosis ; bacteria causing tetanus, diphtheria, pertussis, and tuberculosis are also rod-shaped.

3. Brassica (Brassicaceae, Cruciferae)
A genus of plants belonging to the mustard family Brassicaceae. The whole family includes a total of 376 different genera and 3,200 different species . The family is also known as "Cruciferae" because the four petaled flowers of these plants look like crosses. The plants are distributed worldwide and have annual (living one year), biennial (living two years) and perennial (living many years) members. Member species of genus Brassica include Brassica napus which produces rapeseed or canola oil; Brassica nigra which produces yellow mustard; Brassica oleracea whose subspecies and strains include kale and collard greens (B. oleracea acephala), broccoli (B. oleracea botrytis), cauliflower (B. oleracea cauliflora), head cabbage (B. oleracea capitata), brussel sprouts (B. oleracea gemmifera), and kohlrabi (B. oleracea gongycoides); and Brassica rapa, whose subspecies include pak choi (B. rapa chinensis), Chinese cabbage (B. rapa pekinensis), and turnip (B. rapa rapifera). Also, one subspecies of B. rapa is used as a model organism to study genetics , molecular biology , plant breeding, cell biology , and physiology ; it is called the "rapid cycling" Brassica or RCBr or the Wisconsin Fast PlantTM , and was developed specifically for scientific study. Additionally, the radish Raphanus sativus is a member of the Brassicaceae family. The full taxonom ic classification is kingdom Plantae, division Tracheophyta, subdivision Spermatophyta, class Angiospermae, subclass Dicotyledeonae, order Papaverales, family Brassicaceae.

4. Clostridium
Clostridium is a genus of anaerobic bacteria that produce strong toxins and are responsible for diseases such as tetanus, botulism and gas gangrene.

5. Colonoscopy
This is a procedure involving the insertion of a fiberoptic endoscope of about 1 cm diameter into the anus and advanced through the sigmoid colon, descending colon and the transverse colon up to the caecum. The appearance of the mucosa is observed for inflammation and growths. Samples are often taken for microscopic study. It is a procedure with significant discomfort and sometimes pain. The patient usually receives sedation by intravenous injection. Material effects, risks and side effects: over-sedation causing respiratory depression; biopsied site may bleed; mucosal damage may lead to infections, perforation of the bowel results in intra-peritoneal air and may necessitate emergency laparotomy.

6. Deuterostomes
Animals in which the first opening that appears in the embryo becomes the anus while the mouth appears at the other end of the digestive system . Main groups include chordates and echinoderms.

7. Hemorrhoids
Hemorrhoids are dilated veins in the anus. Internal hemorrhoids: dilated veins of the plexuses of the superior and middle hemorrhoidal veins above the mucocutaneous junction. Internal hemorrhoids drain to the portal vein. External hemorrhoids: dilated veins of the inferior hemorrhoidal plexus below the mucocutaneious junciton the the tissues beneath the anal epithelium of the anal canal. External hemorrhoids drain into the systemic circulation. These veins become symptomatic when the venous pressures increase: such as in constipation, straining to defecate, pregnancy, tumors, and portal hypertension .

8. Herpes simplex virus (HSV1, HSV2)
Herpes is a virus in the family Herpesviridae . Type 1 HSV causes blisters on the lips, nostrils, and possibly on the lining of the eyelids. Type 2 HSV causes blisters and lesions on and around genitalia. Type 2 HSV is a sexually-transmitted disease . The most common symptom is a single blister or cluster of painful blister-like sores. In females the genital lesions appear around the vaginal opening, urethra, anus and buttocks. Burning during urination and abnormal vaginal discharge may occur. Males may develop blisters on the penis and/or around the anus and buttocks. The fluid-filled sores are highly contagious and may last up to three weeks. They will usually crust over, form a scab and then heal completely without scarring. Other symptoms include fever, headache, swollen glands, muscle aches and tiredness. These symptoms are most common during the initial herpes outbreak. Individuals who have sexual contact with an infected partner may develop symptoms within 2-10 days or longer. Herpes is transmitted through the mucous membranes by direct physical contact with an individual who has the blister-like lesions. Oral, anal and genital sexual activity can transmit the virus; using a condom and spermicides during sex can reduce the risk of transmission. The best way to prevent infection is to avoid sexual contact with a person with herpes symptoms. If a pregnant woman contracts herpes, there is a chance that her baby will be infected during delivery if the woman has genital sores.There is currently no cure for herpes, though treatments exist to alleviate symptoms; treaments include the prescription drugs alacyclovir (Valtrex) or Acyclovir (Zovirax).

9. Human papillomavirus (HPV, genital warts)
This virus is a sexually-transmitted infection that causes genital warts and cervical lesions, and is thought to be responsible for most cases of cervical cancer; women whose HPV infections persist over time are thought to be at the greatest risk of cancer. Genital warts can develop on the cervix, penis, or in the urethra, vagina, anus or rectum. They look like other sorts of warts; they are dry and painless, firm and rough in texture, and can be grayish or skin colored. If left untreated, warts can grow together in clumps that resemble tiny pieces of cauliflower. They may itch slightly; flat warts may not be very noticeable. Many people may have this infection and not realize it. HPV is mainly transmitted via sexual intercourse (vaginal, oral or anal intercourse) and it may also be transmitted by sharing damp unwashed articles like washcloths, towels or underwear. The disease is highly contagious, but the risk of transmission can be reduced by using a condom during sex. Treatment involves burning off the warts with liquid nitrogen or lasers or by applying prescription creams (most containing podophyllotoxin )that kill the virus. There are no over-the-counter drugs that can treat this sort of infection.

10. Imperforate anus
An imperforate anus is a developmental anomaly of the anus in which there is no anal opening.
