Genetics
ARC. A gene on chromosome 8q24.3 that encodes a protein required for consolidating synaptic plasticity and forming long-term memory, as well as in stress fibre dynamics and cell migration. It regulates endocytosis of AMPA receptors in response to synaptic activity, and is required for homeostatic scaling of AMPA receptors. ARC also plays a role in regulating cell morphology and cytoskeletal organisation. It is also an older gene symbol for what is now designated as NOL3, see there.

REFLEX ARC FOR PATELLAR TENDON REFLEX

reflex arc

The path followed by a nerve impulse to produce a reflex action. The impulse originates in a receptor at the point of stimulation, passes through an afferent neuron or neurons to a reflex center in the brain or spinal cord, and from the center out through efferent neurons to the effector organ, where the response occurs.
