Part A The mandibular condyle . The mandibular condyle . is the opening through which blood vessels and nerves to the lower lip and skin of the chin pass is the line of fusion between the two halves of the mandible articulates with the temporal bone to form the temporomandibular joint is the opening through which the alveolar nerve passes is the site of insertion for the temporalis muscle.

articulates with the temporal bone to form the temporomandibular joint

Explanation:

The mandible is the lower bone of the lower jaw of the human face which consists of the ramus and the front bones and teeth.

The mandible contains an articular structure for articulation called "condyle" which help in the formation of temporomandibular joints. The temporomandibular joint is the joint formed between the lower jaw or mandible and the temporal bone of the skull. This allows the free movement of the lower jaw.

Thus, the selected option is the correct answer.

Articulates with the temporal bone to form the temporo-mandibular joint.

Explanation:

The mandibular condyle articulates with the temporal bone at the mandibular fossa. The temporal bone consists of concave depression at the squamous portion.

The mandibular condyle and the temporal bone are separated by the articular disc, it divides the joint into two distinct type of compartments. The function of the temporomandibular joint is to connect the jaw bone with the skull.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
