The point where the muscle attaches to the more movable bone in a joint refers to as the insertion. The origin is the point where the muscle attaches to the less movable bone. In general, we can say insertion moves towards the origin. The muscle which is responsible for causing particular movement is called a prime mover.
Through the help of synergists, prime mover produces some movement or reduce the undesired movement. Synergist contain specializes fixators. Fixators function is to stabilize the origin of prime mover so that the tension created can be used to move the insertion bone.
Explanation:
The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.
The essential diagnostic feature of factitious disorder is
that while seeking treatment for themselves or for others after the onset of
injury or disease, individuals with factitious disorder often would falsify
medical or psychological signs and symptoms, either in themselves or in others
that are associated with the identified deception.

Answer;
A skull from genus Homo that dates from approximately 750,000 years ago is discovered. Then the foraman magnum is most likely be located at the bottom of the skull.
Explanation;
Foramen magnum is a large opening at the base of the skull through which the spinal cord exits the cranial vault. It is situated in the occipital bone, and forms around the base of the brainstem, separating the brain from the spinal cord. In apes and humans (members of genus homo) it is formed by the fusion of the four parts of the occipital. In human for example; it is anteriorly positioned, with its interior lying on the bitympanic line and is also inferiorly oriented.
