The nervous system is divided into the central nervous system (CNS) & peripheral nervous system (PNS). The brain and the spinal cord comprise the central nervous system. The peripheral nervous system serves the rest of the body and they branch from the spinal cord. Ii is in the peripheral nervous system that you'll find motor and sensory neurons. The sensory neurons take information to the CNS to be processed. After processing information, the CNS sends back information through the motor neuron of the PNS indicating which action to be taken based on the ‘input’ information.
If during the vaginal cephalic delivery, there is a requirement of additional obstetric maneuvers after the head of the fetus has been delivered however the gentle traction is failed then this condition is known as shoulder dystocia.
Shoulder dystocia occurs when the shoulder of the baby gets stuck in the pubic bone of the mother after the head has been delivered due to which the baby retracts his head back into the birth canal.
Gestational diabetes is one of the conditions that impose a risk on the baby to have shoulder dystocia during the delivery.
Since in the given question it is mentioned that the mother has gestational diabetes and the head has been delivered but seems to retract back, this points out that the condition suspected is shoulder dystocia.
