Phalanges, the digits of the hand, are the most distal bones of the upper limb. They articulate with the metacarpals, the bones of the hand, which in turn articulate with one of two rows of carpals, the bones of the wrist. Next is the radius, the bone of the lateral side of the forearm, which articulates with the humerus, the bone of the upper arm, which articulates proximally with the scapula and distally with the radius and ulna.

The head of the humerus articulates proximally with the scapula at the glenoid fossa. It articulates distally with the radius and ulna. The carpals are the bones of the wrist; they do not articulate with the humerus.

The carpals make up the wrist. The metacarpals make up the body of the hand. The tarsals and metatarsals make up the ankle and the body of the foot, respectively.

The crista galli is the part of the ethmoid bone that is a point of attachment for the meninges of the brain. The crista galli is the most superior point on the ethmoid.

There are four paranasal sinuses in the head: the frontal, maxillary, sphenoid, and ethmoid sinuses. They function in lightening the skull, and creating mucous for the nasal cavity. The temporal bone does not contain a sinus.

While many bones are responsible for the formation of the orbit, it is the zygomatic bones that make up the lateral portion of the orbitals. You can remember this by keeping in mind that the zygomatic bones are also called the cheek bones, and are on the lateral sides of your face.

The frontal bone forms the superior region of the orbital, and the lacrimal bone forms the medial border. The maxillary and zygomatic bones each form part of the inferior border, with the zygomatic bone extending into the lateral border. The sphenoid and ethmoid bones both form the posterior wall, with the sphenoid region lateral to the ethmoid region.

The parietal bones of the skull reside over the parietal lobes of the brain. The parietal lobe is just on top of the occipital lobe and is responsible for various sensory information processing. The parietal bones of the skull lie on either side of the head, slightly posterior to the ear area, and meet on top of the head.

The coronal suture is the area at the "top" of the skull where the parietal bones and the frontal bones meet, and is not normally closed at birth (thus, the traditional "soft spot" near the exact top of a newborn's head).

Remember that the coronal plane traverses the body from left to right, separating the anterior and posterior dimensions. As such, the coronal suture can be expected to fall within this plane.

The sphenoid bone, located posterior and inferior to the face, supports most of the immovable bones of the face and is thus critical to the development of facial structure. The bone also contains two "wing" projections that curve towards the sides of the skull, which may help to stabilize the cranium during lateral impacts, and the sella turcica, a concave space that houses the pituitary gland.
