Anatomical terminology |
The pectinate line (dentate line) is a line which divides the upper 2/3s and lower 1/3 of the anal canal. Developmentally, this line represents the hindgut-proctodeum junction.
It is an important anatomical landmark, and several distinctions can be made based upon the location of a structure relative to this line:
Distinction |
Above pectinate line |
Below pectinate line |
destination of lymph drainage |
internal iliac lymph nodes,[1] inferior mesenteric lymph nodes[2] (pararectal lymph nodes), |
superficial inguinal lymph nodes (below Hilton's white line)[3] |
epithelium |
columnar epithelium (as is most of the digestive tract - the line represents the end of the part of the body derived from the hindgut) |
stratified squamous epithelium, non-keratinized (until Hilton's white line, where the anal verge becomes continuous with the perianal skin containing keratinized epithelium.) |
embryological origin |
endoderm |
ectoderm |
artery |
superior rectal artery |
middle and inferior rectal arteries |
vein |

- quoted from http://en.wikipedia.org/wiki/Long_interspersed_nucleotide_elements#LINEs
- Long interspersed nuclear elements[8] are a group of genetic elements that are found in large numbers in eukaryotic genomes. They are transcribed (or are the evolutionary remains of what was once transcribed) to an RNA using an RNA polymerase II promoter that resides inside the LINE. LINEs code for the enzyme reverse transcriptase, and many LINEs also code for an endonuclease (e.g. RNase H). The reverse transcriptase has a higher specificity for the LINE RNA than other RNA, and makes a DNA copy of the RNA that can be integrated into the genome at a new site.
- The 5' UTR contains the promoter sequence, while the 3' UTR contains a polyadenylation signal (AATAAA) and a poly-A tail.[10] Because LINEs move by copying themselves (instead of moving, like transposons do), they enlarge the genome. The human genome, for example, contains about 20,000-40,000 LINEs, which is roughly 21% of the genome.
