Question

Lower jaw in mammals articulates with a bone called:
A. Jugal
B. Alisphenoid
C. Squamosal
D. Parietal

Answer 1

Hint: The lower jaw in mammals is connected to the temporal bone of the skull by a joint called the temporomandibular joint (TMJ). This joint is a synovial joint, which allows for movement of the lower jaw in a variety of directions. The joint is composed of two parts: the mandibular condyle, which is part of the lower jaw, and the mandibular fossa, which is part of the temporal bone.

Complete Step by Step Answer:
In animals, the squamosal bone serves as the point of articulation for the lower jaw. This means that the lower jaw can move up and down, side to side, and rotate around its vertical axis. The squamosal helps reduce the amount of stress on other parts of the skull during chewing and speaking, which is important for humans because we use our mouths a lot.
In humans and some other primates (such as chimpanzees), both jaws are movable because their brains require two sets of teeth: one set for eating meat and another set for grinding plant food. In these species, the ability to chew effectively relies heavily on coordination between the movements of the upper jaw (maxilla) necessary to locate prey items in front of your face using your eyesight, plus direct control over those same muscles from below via transmitted forces through attachment points at either end of your maxilla—directly onto bones above or below corresponding molars or incisors.
Basically, this allows us to eat hard things like nuts or seeds without having metal bits come loose into our food later.
Hence, option C is correct.

Note: The squamosal or squamous suture is the line of connection between the temporal and parietal bones at the sides of the skull. It is a jagged line that helps the skull grow by expanding as the brain develops during growth.
