Benign fasciculation syndrome: Benign fasciculation syndrome (BFS) is a neurological disorder characterized by fasciculation (twitching) of various voluntary muscles in the body. The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, legs, and feet.Axon guidance: Axon guidance (also called axon pathfinding) is a subfield of neural development concerning the process by which neurons send out axons to reach the correct targets. Axons often follow very precise paths in the nervous system, and how they manage to find their way so accurately is being researched.SuccinylmonocholineL1 (protein): L1, also known as L1CAM, is a transmembrane protein; it is a neuronal cell adhesion molecule, member of the L1 protein family, of 200-220 kDa, and involved in axon guidance and cell migration with a strong implication in treatment-resistant cancers.Arc system: The Arc system stands for Anoxic Respiratory Control system. It is an example of a two-component system, in that it has a sensor molecule and a response regulator.Collapsin response mediator protein family: Collapsin response mediator protein family or CRMP family consists of five intracellular phosphoproteins (CRMP-1, CRMP-2, CRMP-3, CRMP4, CRMP5) of similar molecular size (60–66 kDa) and high (50–70%) amino acid sequence identity. CRMPs are predominantly expressed in the nervous system during development and play important roles in axon formation from neurites and in growth cone guidance and collapse through their interactions with microtubules.Fasciclin 2: Fasciclin 2 (Fas2 or FasII) is a 95 kilodalton cell membrane glycoprotein in the immunoglobulin (Ig) – related superfamily of cell adhesion molecules (CAMs).L.CrampFields' disease: Fields' disease is considered to be one of the rarest known diseases in the world, with only two diagnosed cases in history. It is named after Welsh twins Catherine and Kirstie Fields.Renshaw cell: Renshaw cells are inhibitory interneurons found in the gray matter of the spinal cord, and are associated in two ways with an alpha motor neuron.Aging movement control: Normal aging movement control in humans is about the changes on the muscles, motor neurons, nerves, sensory functions, gait, fatigue, visual and manual responses, in men and women as they get older but who do not have neurological, muscular (atrophy, dystrophy...) or neuromuscular disorder.Abducens nucleus: The abducens nucleus is the originating nucleus from which the abducens nerve (VI) emerges - a cranial nerve nucleus. This nucleus is located beneath the fourth ventricle in the caudal portion of the pons, medial to the sulcus limitans.Juvenile primary lateral sclerosis: Juvenile primary lateral sclerosis (JPLS) , also known as primary lateral sclerois (PLSJ), is a rare genetic disorder, with a small number of reported cases, characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. The disorder damages motor neurons, which are specialized nerve cells in the brain and spinal cord that control muscle movement.Pang Hui: Pang Hui was a military general of Cao Wei during the Three Kingdoms era of Chinese history. He was the son of Pang De, and inherited his father's courage and ferocity in battle.Vomeronasal organ: The vomeronasal organ (VNO), or the Jacobson's organ, is an auxiliary olfactory sense organ that is found in many animals. It lies close to the vomer and nasal bones.Cranial nerve examination
