Do humans have a tectum?

As a professional in the field of cryptocurrency and finance, I must admit that the topic of human anatomy is not typically within my domain of expertise. However, if we approach this query with a similar investigative mindset as we do in finance, I would pose the question: "Do humans possess a tectum, and if so, what is its function and location within the body?" This inquiry seeks to bridge the gap between two seemingly disparate fields, finance and biology, in order to gain a deeper understanding of the human body and its intricate systems.
