Compare the types of neurons that synapse int he posterior l

D. Application and Analysis 1. Starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, nal nerve, nerve plexus, and specific peripheral nerve involved in the pathway. 2. Compare the types of neurons that sy in the p lateral, and anterior gray horns of the spinal cord. E. Clinical Challenge 1. How can an injury to a peripheral nerve cause loss of both sensory and motor functions? 2. How does the stretch reflex cause the quadriceps femoris muscle group to contract? 3. A woman injures her neck in a car accident and now has difficulty breathing. Which spinal nerves may be involved in this case?

Solution

The anterior grey column has somatic motor neurons which used to sensing of skeletal muscles and pain and temperatures. The lateral grey column has preganglionic visceral motor neurons which project to the sympathetic ganglia. The ventral grey column has cell bodies of motor neurons which is also used to sensing striated muscle via spinal nerves. All are related to functioning for skeletal muscles which are also called as striated muscles.
