What do we call nerves that supply on the skin? Correct Answer cutaneous nerves cutaneous nerves usually contain what peripheral spinal nerves? Correct Answer GSA, GVA, and GVE What do we call an area of skin innervated by a specific cutaneous nerve? (can overlap) Correct Answer cutaneous area Does a cutaneous area's cutaneous nerve have to originate from a single spinal nerve or can it come from a plexus of more than one spinal nerve? 2 / 24 Correct Answer either adjacent dermatomes and cutaneous zones usually what? Correct Answer overlap What do we call an area of skin innervated by a one single cutaneous nerve (can originate from one or a plexus of spinal nerves?(no overlap) Correct Answer autonomous zone radial nerve comes from 3 spinal nerves so it will have how many dermatomes? Correct Answer 3 dermatomes Knowing positions of dermatomes and autonomous zones is useful how?- Correct Answer to assess PNS sensory functioning 3 / 24 Are all autonomous zones the same across species or do they vary? Correct Answer they vary What are the three types of nerve fibers are there? Correct Answer afferent, efferent, and integrating fibers Which fibers connect afferent fibers with processing centers or efferent fibers? Correct Answer integrating fibers What is an example of integrating fibers? Correct Answer interneurons Which fibers send info from periphery to CNS to higher centers for processing? Correct Answer afferent/sensory fibers 4 / 24 Which fibers send info from motor planning centers through the CNS to connect with other motor fibers to take info to the periphery? Correct Answer efferent/motor fibers motor neurons (efferent neurons) are separated into two separate types of motor neurons. What are they? Correct Answer Upper motor neurons (UMN) and lower motor neurons (LMN) What are the UMN confined to location wise? Correct Answer CNS and its axons (brain, down spinal cord, to LMN) The UMN axons influences activity in what? Correct Answer LMN what is the manager of motor systems? Correct Answer UMN Where are LMN found? 5 / 24 Correct Answer cranial nerves and spinal nerve
