Description
In this report, use your knowledge from the unit 3 report and describe in detail on what nerve innervates those muscles/groups of muscle to produce the following movements
1. Stand up from a sitting position
Part B. 1. Which cranial nerve affects taste?
2. Which cranial nerve is concerned with the maintenance of balance?
Part C. On the way to the doorknob, Matt stepped on a sharp nail. 1. What type of reflex will he trigger?
2. Describe the pathway from stepping on the nail to withdrawing his foot from the stimulus.
All reports will be worth 4% of your grade and will be 5 points each. In order to successfully earn all 5 points you will need to:
1. Answer all questions thoroughly and completely.
2. Use at LEAST 3 different references (can include information from the Primal website as a source). The references needs to be listed in a "Works Cited" section at the end of the report. Please note: Wikipedia does not count as a reference.
3. Give credit to all sources used- citing correctly and PARAPHRASING any information taken from an outside source. Please do not copy and paste any information, even if you cite the source. Your report will be submitted through Turnitin and will allow us to see what sources were used and the exact information you took from that source- BE CAREFUL!
4. Must have a minimum of 500 words and can be in essay form OR question and answer form. (500 words not including the topic/questions given)
5. Must be turned in at 11.59 PM on the date it is due. PLEASE avoid turning in your report close to the 11.59 PM deadline. There have been many issues with submissions in the past due to high volume of students submitting at the same time. Late assignments will be deducted 2.5 points.

Anatomy
Part A
1. Stand up from a sitting position
Standing up requires signal to be transmitted from the brain, to the feet, and all the way to the
vertebral column. A motor input generated in the cerebellum is sent to the cerebral cortex via the
motor fibers. The fibular and tibial nerves alert the knee joint and ankle joint. Then, the
cerebellum controls muscle movement; thus, enhancing body balance. The pedicle nerve sends
signals to the spinal cord; thus, allowing the standing action.
2. While standing upright, turn around 180 degrees to face opposite direction
Usually, all muscles from the head to toe are required to turn the body around 180 degrees to
face a different direction. First, to rotate the head various muscles such as Scalene and Splenius
capitis are involved. Second, the accessory nerves play a significant role in enhancing the
movement of the head through one-hundred and eighty degrees. Third, the Iliacus and Psoasa
major are crucial in ensuring lower limbs rotate as required.
3. Jumping over the couch and taking several steps forward
Surname 2
First, when jumping over the couch, the glutes pushes one leg forward. Usually, taking several
steps forward requires a person to lift one leg at a time to carry body weight and gain balance.
Thus, the hip tilts sideways, which allows the knee to bend. Second, the semitendinosus and
semimembranosus muscles of the stretched leg relax. Equally, flexion of the leg is enhanced by
the rectus femoris and sartorius muscles. Third, the semimembranous, semitendinosus and biceps
femoris allow the extension of the lower leg readying it for action.
4. Reach forward and grasp a door knob
First, the ocular motive nerves allow eyes to move and determine the position of the knob. The
signal is communicated to the cerebellum and the command to allow motion is sent to the spinal
cord before it is transmitted to the arm. Second, the rotator cuff muscles and the infraspinatus
muscles enhance the movement of the glenohumeral joint. After the forearm extends to the
doorknob with the action of the humerolunar joint and the humeroradial joint, the hand feels
pressure on fingers and thumb. Third, the encapsulated nerve endings found on the skin send
information concerning how tight the person has head the doorknob to the brain.
5. Turn a door knob 180 degrees clockwise
First, turning the doorknob 180 degrees is possible after rotating the forearm within the same
angle. Second, the tight grip on the doorknob allows the palm to rotate upward; thus, enhancing a
clockwise movement. Second, the supinator and Biceps brachii muscles enhance the arm to
undergo supinati...
