CHAPTER 13
Muscles and nerves exhibit similarities in structure and nomenclature. Drag each label into the appropriate position to identify the neural structure that would correspond to the muscular image.
Answer: 1. epineurium/ epimysium 2. Nerve/muscle fascicle 3. perineurium / perimysium 4. endoneurium/ endomysium 5. muscle fibers 6. nerve fibers Rationale: The above given diagram shows the layers of the muscles. Each specific muscles had this structure and layers. This layers mainly classified as three ; we can see this in answer 1, 3, 4 . 1- this is the layer which is near to the bone which means outer part of the muscle. This contains (2) - nerve / muscle fascicles ( blood vessels located in those areas to supply the region of the muscles) 3- This layer consists of muscle fibers 4 - this is the innermost layer of the muscle fibers.

Which of the following statement(s) is/are true regarding the general anatomy of the nerve plexuses? Check all that apply.
The posterior cord of the brachial plexus is formed by three posterior divisions. The cervical plexus receives fibers from the anterior rami of nerves C1 to C5. The coccygeal plexus is formed from the anterior rami of S4, S5, and Co.
Reflexes have four important properties: they require stimulation, they are quick, they are involuntary, and they are stereotyped.
TRUE
The spinal cord serves four principle functions: conduction, neural integration, locomotion and reflexes.
TRUE
