Final answer:
Dense connective tissue, such as tendons and ligaments, does contain some nerve endings that can provide sensory information, including pain and proprioception, but its primary function is not nervous signal reception or processing.
Step-by-step explanation:
The question you have posted regards whether dense connective tissue receives nervous input. Connective tissue proper, including dense connective tissue, provides structure and strength to various parts of the body, like tendons and ligaments, due to bundles of fibers such as collagen and sometimes elastin. It is divided into dense regular connective tissue and dense irregular connective tissue based on fiber orientation.
While dense connective tissue is rich in fibers that provide elasticity and protection, it does not have a primary role in receiving or processing nerve signals. However, the tissue can contain nerve endings that allow it to send pain and proprioceptive signals, hence there is some level of nervous input. Dense irregular tissue, found in the dermis, is rich in collagen fibers and supports the skin, and while not its main function, may also contain nerves for sensation.
