A tower of histological giraffes to celebrate #WorldGiraffeDay

1. Brenner tumor
The head of this giraffe is composed of urothelial-like cells (the cells that normally line the bladder and ureters. However, the strange thing about them is that they were found in the ovary. Original 📷 by @DrAldehyde via Twitter
2. Endocervix
The region of the neck of the uterus that is continous with the inner lining of the uterus. The transition between endocervix and ectocervix undergoes a lot of change during life and is the region most susceptible to cell changes that cause cancer. Original 📷 by @jestevamd
3. Smooth muscle
Smooth muscle is a muscle that contracts involunatrily and usually around tubes to move stuff through them or maintain pressure. They are ‘spindle’ shaped cells (fat in the middle and tapering at each end) with a centrally located, cigar-shaped nucleus. This means that the cells look different depending on if you slice them along their length (longitudinal section) or across their width (transverse section). You can see examples of both in this image. Original 📷 by @onlyfornursed via FB
4. Cervical vertebra
The pink stuff is the cancellous/spongy bone of the vertebra and the white space (that makes the shape of the giraffe) is the medullary cavity where the bone marrow lives. The irony that a cervical vertebra is a bone in the neck is not lost on me! Original 📷 by I Heart Histo - Histology
5. Mammary Gland
This image shows a biopsy obtained from a mammary gland during pregnancy. You can tell because the breast contains a high ratio of glandular tissue (the many purple circles) to connective tissue (the pale pink stuff surrounding the glands). The glands are producing (but not yet releasing) milk. In addition, the ducts of this breast are developed. The entire giraffe is a formed from a lactiferous duct surrounded by connective tissue.
