[blank_start]Long bones[blank_end] are longer tan they are wide and include the bones of the upper and lower limbs, excluding the ankle and wrist bones.

[blank_start]Flat bones[blank_end] are shaped exactly as they're named. These bones include the ribs, sternum, certain skull bones, and hip bones.

[blank_start]Irregular bones[blank_end] are those whose shape doesn't fit into any of the other classes. These bones include the vertebrae, the sacrum, and certain bones of the skull, such as the sphenoid bone.

[blank_start]Sesamoid bones[blank_end] are usually small, round, and flat, and shaped somewhat like a sesame seed.

[blank_start]Sutural bones[blank_end], or Wormian bones, are small, flat, irregularly shaped bones between the flat bones of the skull. There are individual variations in the number, shape, and position of the sutural bones.

The axial skeleton consists of

The appendicular skeleton consists of

The vertebral column consists of 24 unfused vertebrae and 5 fused vertabrae of the sacrum and coccyx. Of the 24 unfused vertebrae, [blank_start]7[blank_end] are cervical, [blank_start]12[blank_end] are thoracic, and [blank_start]5[blank_end] are lumbar.

[blank_start]C1[blank_end], or [blank_start]atlas[blank_end], articulates with the occipital condyles, and holds up the head. It also allows us to nod our head yes.

[blank_start]C2[blank_end], or [blank_start]axis[blank_end], fuses with C1 and allows us to rotate our head left and right.

Ribs 1-7 are considered [blank_start]true ribs[blank_end], or vertebrosternal ribs, because they attach directly to the sternum by their own costal cartilage. Ribs 8-12, on the other hand, are classified as [blank_start]false ribs[blank_end] because they lack this direct attachment to the sternum. Ribs 8-10 are [blank_start]vertebrochondral ribs[blank_end] as they have an indirect attacment to the sternum, as their cartilage attaches to the costal cartilage of the true ribs. Ribs 11-12 have no attachment to the sternum at all, so they are often referred to as [blank_start]floating ribs[blank_end] or vertebral ribs.

[blank_start]Fibrous joints[blank_end] consists of two bones joined by short collagen fibers. Most [blank_start]fibrous joints[blank_end] allow no motion. [blank_start]Cartilaginous joints[blank_end] consist of bones united by cartilage rather than fibrous connective tissue. Most [blank_start]cartilagenous joints[blank_end] allow some motion. [blank_start]Synovial joints[blank_end] are freely movable joints.

Fibrous joints include

Cartilaginous joints include

Synovial joints include

The cartilagenous connection between the ends of ribs 1 and 2 to the manubrium and sternum is an example of syndesmosis.

Gomphosis is a type of joint that binds what to what?

Bones connected by a ligament, such as the distal joint between the tibia and fibula is an example of syndesmosis.
