Relative to muscles of the back, we have more dexterity and precision in the control of our fingers. This is explained by: A) The fact that muscles of the back are under autonomic control B) The smaller ratio of muscle fibers controlled by neurons in the fingers C) The fact that finger muscles are smaller D) The smaller threshold potential of finger muscles

a) Describe how the isolated muscle behaved as the interpulse interval was decreased progressively. b) Examine the table. Can you describe what happens to the frequency of stimulation when you decrease the interval between the pulses?
The role of muscle spindles in the maintenance of the upright posture depends upon all the following, except :-a- contraction of the peripheral contractile part of spindle fibersb- increased sensory discharge from spindles of postural musclesc- increased supraspinal facilitation to the γ-motor neurons of postural musclesd- presence of greater numbers of spindles in postural muscles
Please order the steps of voluntary movement. 1) Primary motor cortex sends information to alpha motor neurons 2) The prefrontal and parietal cortices decide to initiate movement. 3) Alpha motor neurons initiate muscle contractions. 4) The supplementary motor area (SMA) uses input from the thalamus and basal ganglia to plan a movement.
To demonstrate muscle fatigue, a student held an 8 lb dumbbell in her hand and abducted her arm parallel to the floor. After 45 seconds, she has having difficulty holding that position so she rotated her hand 90 degrees. This allowed her to hold the dumbbell in position for an additional 20 seconds. Which of the following is the best explanation for this? A. Different motor units were contracting while others were relaxing. B. Muscles began to contract isotonically rather than isometrically. C. The load was reduced. D. The resistance to contraction was reduced. E. The change in position provided a greater range of motion at the shoulder.
Why is an interneuron needed to provide reciprocal inhibition of the flexor muscle when an extensor muscle is activated?
Which of the following statements are true of the location and function of muscles? a) The rectos abdominis extends the vertebral column. b) The triceps brachii flexes the forearm. c) The quadriceps lemons extends the thigh. d) The gastrocnemius plantar flexes the foot. e) The gluteus maximus extends the thigh. f) The trapezium raises the shoulder. g) The latissimus dorsi flexes the upper arm. h) The masseter closet the jaw. i) The sternocleidomastoid extends the head. j) The orbicularis oculi opens the eye. k) The gluteus medics abducts the thigh. I) The sartorius extends the lower kg.
Strabismus is an eye condition in which one eye is not aligned correctly (see pictures below). One treatment is to inject botulinum toxin (Botox) into eye muscles to correct the misalignment. Considering the effects of botulinum toxin on the neuromuscular junction we have learned, which muscle would you inject the toxin (A-D)? Briefly explain the molecular mechanism underlying this treatment. Left eye Right eye Normal eye alignment Left eye Right eye A B C D D Strabismus
If you were doing sit-ups, which muscle group would you be working the most (if you were using correct form)? A) Gluteus MaximusB) QuadricepsC) Rectus AbdominusD) Biceps
a) Describe the processes involved in the knee-jerk reflex and explainwhy it is called a ‘monosynaptic’ reflex.b) While crawling across the floor a child accidentally places her righthand onto a piece of broken glass. How will the flexor muscles of herleft arm respond? What happens to the rest of her body?
Doing the doggy hydrant exercise would work this muscle the most: A) TricepsB) SartoriusC) Pectoralis MajorD) Gastrocnemus
A tap on the patellar tendon at the knee joint is used to test the knee-jerk reflex. All of the followings are correct, except ---------------------. The reflex starts with the 1a sensory neurons of the muscle spindle There is an excitatory stimulus to the motor pool of the extensor muscle There is a stimulation of the excitatory interneuron of the flexor muscle Excitation of the extensor muscle fibers causes the knee extension Muscle contraction depends on coordination between motor pools of antagonistic muscles
