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

Solution

1. It would cause sensory loss and motor loss because that specific body part is supplied by a motor pathway such as corticospinal and a sensory pathway such as spinothalalmic.

2. The rectus femoris differs from the other quadriceps muscle in that it crossesThe rectus femoris differs from the other quadriceps muscle in that it crossesThe rectus femoris differs from the other quadriceps muscle in that it crosses both the hip and the knee joints. Thus, it causes both flexion of the hip and extension of the knee.
