An occupational therapist can provide the right intervention for this. Intervention may include ocular motor and strengthening activities to promote the development of muscle control of the eyes in order to improve eye tracking. For more information on oculomotor control/dysfunction read here. To talk to an occupational therapist, click below.
Digestive system The gut of the earthworm is a straight tube which extends from the worm's mouth to its anus. It is differentiated into a buccal cavity (generally running through the first one or two segments of the earthworm), pharynx (running generally about four segments in length), esophagus, crop, gizzard (usually) and intestine.
Structure. The primitive brain of the earthworm consists of two cerebral ganglia. Sensory nerves leave the brain and run forward to the first segment in the earthworm's body. The nerve cord travels from this first segment to the last.A fibrous sheath surrounds the nerve cord.hile humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side.
