An inertial measurement unit works by detecting the current rate of acceleration using one or more accelerometers, and detects changes in rotational attributes like pitch, roll and yaw using one or more gyroscopes. And some also include a magnetometer, mostly to assist calibration against orientation drift.
In the human there are 31 pairs of spinal nerves, one on each side of the vertebral column. These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine.
The nerve also contains fibers bringing sensation from the face to the Pons. It is the largest of the cranial nerves and forms three divisions: Opthalmic division (V1) - from skin of anterior scalp, upper eyelid, nose, nasal cavity mucosa and lacrimal gland through superior orbital fissure.ranial Nerves. There are 12 pairs of cranial nerves and because they are nerves, they are considered to be a part of the peripheral nervous system (PNS). Conventionally, each of the 12 pairs of nerves is named using a Roman numeral (I through XII) together with the descriptive name for the nerve.
