text: Yo, check it out, we 'bout to break it down,
  Analyzin' them primate condyles all around.
  Immunohistochemical techniques, that's the game,
  Examining collagen types and glycosaminoglycans, no shame.
  
  Two female rhesus monkeys in the mix,
  Macaca mulatta, they got the tricks.
  Juvenile monkey showin' weak collagen Type I and III,
  Fibrous tissue layer, not the place to be.
  
  Pre-cartilaginous tissue layer, that's where it's intense,
  Cartilaginous tissue layer, a little less dense.
  Posterosuperior and posterior regions bring the heat,
  More intense staining there, the anterior takes a seat.
  
  Cartilage-characteristic extracellular matrices on display,
  Type II collagen and keratan sulfate, here to stay.
  Posterior condyle, that's where they shine,
  Cartilaginous tissue layer, that's the prime.
  
  Late-adolescent monkey, a whole new phase,
  Anterior half of the condyle, it's a maze.
  From anterior to posterosuperior, the intensity grows,
  Posterior region, not as intense, it shows.
  
  Posterosuperior region, that's where it's at,
  Extracellular matrices, puttin' on a hat.
  Variations in expression, regional and grand,
  Mandibular condyles, they understand.
  
  Different developmental stages, they play a role,
  Competin' growth and articulatory functions, takin' control.
  These variations reflect what's goin' on,
  In them primate condyles, where the magic's drawn.
