Abstract:
Isolated traumatic medial rectus palsies associated with closed head injury is rarely reported in literature. We report the case of a 48 year-old male with an isolated right medial rectus palsy following a mechanical fall with occipital headstrike. Bifrontal and bitemporal haemorrhagic contusions were seen on computed tomography (CT). Magnetic resonance imaging (MRI) revealed a T2 hyperintense lesion at the right paramedian dorsal midbrain, with changes on diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC), suggestive of ischaemic changes in the oculomotor nucleus. He was followed up at two- and six-weeks.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...
