Answer:
FALSE
Explanation:
Luteinizing hormone, also known as the lutropin, is a heterodimeric glycoprotein produced by the gonadotropic cells of the anterior pituitary gland.
The function of the luteinizing hormone in males is the secretion of the progesterone hormone. Whereas, in females, the acute rise of this hormone triggers ovulation, maintains the corpus luteum and is also responsible for the secretion of progesterone hormone.
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.

Microfilaments
Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.
Microtubules
Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on. Microtubules also form the spindle fibers for separating chromosomes during mitosis. When arranged in geometric patterns inside flagella and cilia, they are used for locomotion.
