Otolith organs are able to sense gravitational changes and linear acceleration that comes from movement in a straight line. Also called the utriculus, the utricle occupies the bony labyrinth of the inner ear, nestled between the cochlea and the semicircular canals. Otolithic organs detect movement depending on their orientation. Animals or humans without otolithic organs are imbalanced. The utricle detects movement on the horizontal plane of the head, and the saccule detects vertical motion. The utricle is composed of a mass of tiny calcareous stones covered in hair cells embedded in a jelly-like substance containing the calcareous stones.
While it may be possible to detect a pregnancy as early as 5 1/2 weeks. Because the tiny sac containing the baby and its heart is so tiny, an ultrasound may not be able to detect pregnancy at this stage. If the baby can be seen at 6 to 7 weeks, their heart beat may even be detected. Between 7 and 8 weeks, the baby and their heart beat can both be detected relatively easily. After the 8th week of pregnancy the heart beat and the baby can be clearly seen.
