The geniohyoid muscle is innervated by fibres from the first cervical spinal nerve travelling alongside the hypoglossal nerve. [2] [4] [5] Although the first three cervical nerves give rise to the ansa cervicalis, the geniohyoid muscle is said to be innervated by the first cervical nerve, as some of its efferent fibers do not contribute to ansa cervicalis.
Collectively they are also known as the genial tubercle, [1] genial apophysis and the Latin name spinae mentalis. The inferior mental spines are the points of origin of the geniohyoid muscle, [2] one of the suprahyoid muscles, and the superior mental spines are the origin of the genioglossus muscle, one of the muscles of the tongue. Mental ...

The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid, mylohyoid, and digastric muscles (the lateral pterygoid may play a role).

The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. [1] C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami). It originates from the spinal column from above the cervical vertebra 1 (C1). [2]
This is one of the major advantages; the mathematical model that supports the PAMs functionality is a non-linear system, which makes them much easier [citation needed] than conventional pneumatic cylinder actuators to control precisely. The relationship between force and extension in PAMs mirrors what is seen in the length-tension relationship ...
Walmart has declared 12 stock splits since its IPO. Most were 2-for-1 splits, but the exception was February's 3-for-1 split. Every time a 2-for-1 split occurred, your share count doubled, and the ...
