Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles

of the leg.
Biology

EleoNora [17]3 years ago

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

The term meaning situated nearest the midline or beginning of a body structure is __________.
Dmitriy789 [7]
The term meaning situated nearest the midline or beginning of a body structure is proximal. Proximal is a medical term frequently used to mention to the distance of a body part such as shoulder, elbow, wrist, hand, fingers etc. in respects to its contiguity from the center of the body, normally the torso. In most circumstances, torso as the center point and the arms and legs as connections that prolong from the center. The further away an attachment or body part is from the center shoulder, elbow, wrist, hand, fingers the more distal it is and the closer the body part is to the center the more proximal it is. Therefore, when looking at the center of the human body, the shoulder is proximal in closer proximity to the torso when related to the elbow which is further away.

If a mother has a blood type AB+- and her father has a blood type B- and she marries a man with O- blood type. What is the perce
Marina CMI [18]
Genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is typeAB.

If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents. 
So the chance of alleles OO is 25% × 25% = 6.25%, 
alleles AA is 75% × 75% = 56.25%, 
alleles AO is 75% × 25% = 18.75%, 
alleles OA is 25% × 75% = 18.75%.
Since AA, AO and OA are blood type A, and OO is blood type O, thus their child has 6.25% chance to be blood type O and 93.75% chance to be blood type A. 

The +/- is called the rhesus factor, with + being dominant, and - being recessive.
So if both parents are -, the kids are always -, otherwise the kids might be + or -.
