The frontal bone is a single, unpaired bone that forms the forehead and the anterior part of the cranial vault. [9, 12] The parietal and temporal bones are paired, with one on each side of the skull. The occipital bone is also a single bone, but it forms the posterior aspect of the cranium. [8]

The subtalar joint, formed by the articulation of the talus and calcaneus, is primarily responsible for the movements of inversion and eversion of the foot. The talocrural (ankle) joint is a hinge joint mainly for dorsiflexion and plantarflexion.

Dendrites are the branched, tree-like extensions of a neuron that receive chemical signals (neurotransmitters) from other neurons. They act as the primary input region of the neuron, transmitting these impulses towards the cell body. This makes dendrites the specific area responsible for receiving incoming signals.

In anatomical terminology, the word 'mental' specifically refers to the chin. This term is derived from the Latin word 'mentum,' which means chin. Therefore, any anatomical structures or regions described as mental are associated with the chin area of the face.

A coronal, or frontal, plane divides the body into anterior (ventral) and posterior (dorsal) portions. This imaginary plane runs vertically, perpendicular to the sagittal plane. It effectively separates the front of the body from the back, providing a fundamental anatomical orientation.

The tibialis anterior dorsiflexes and inverts the foot.
