Muscles And Bones Of The Face

The skull is the correct answer because it is the bony structure that forms the framework of the head. It protects the brain and supports the face, providing structure and shape to the head. The skull consists of several bones that are fused together, including the cranium and the facial bones.

The frontal bone forms the forehead. It is a large bone located at the front of the skull, extending from the top of the eye sockets to the hairline. It helps protect the brain and supports the structures of the face. The forehead is the area above the eyes and between the hairline and eyebrows.

The temporal bones form the side of the head. They are located on each side of the skull and contribute to the overall structure and shape of the head. The temporal bones house important structures such as the middle and inner ear, as well as the temporomandibular joint (TMJ) which allows for movement of the jaw. They also provide protection to the brain and play a role in supporting the facial features.

The Mandible bone forms the lower jaw. It is the largest and strongest bone in the face and plays a crucial role in biting, chewing, and speaking. It is connected to the skull by the temporomandibular joint and houses the lower teeth. The mandible also provides support to the muscles of the face and helps in facial expressions.

The zygomatic bones form the cheeks. These bones are also known as the cheekbones or malar bones. They are located on each side of the face, just below the eyes, and extend towards the ears. The zygomatic bones contribute to the prominence and structure of the cheeks, giving the face its characteristic shape.

The occipitofrontalis muscle is responsible for moving the scalp and lifting the eyebrows. It is a broad muscle that covers the top of the skull and consists of two parts: the occipital belly and the frontal belly. The occipital belly is located at the back of the head and connects to the occipital bone, while the frontal belly is located at the front of the head and connects to the skin of the eyebrows. When the occipitofrontalis muscle contracts, it pulls the scalp backward, causing the eyebrows to lift.

The correct answer is Obicularis oris. The obicularis oris is the circular muscle that surrounds the mouth. It is responsible for puckering and closing the lips, as well as controlling the movements of the mouth during speech and eating. The temporalis is a muscle located in the temple region of the skull and is involved in jaw movement. The trapezius is a large muscle in the upper back and neck region, responsible for shoulder movement and stability. The obicularis oculi is a muscle that surrounds the eye and is responsible for closing the eyelids.

The maxillae are the bones that form the upper jaw. They are two large, irregularly shaped bones that fuse together to form the central portion of the facial skeleton. The maxillae are responsible for supporting the upper teeth and play a crucial role in the formation of the facial structure. They also contribute to the formation of the nasal cavity and the floor of the eye socket.

The nasal bones form the bridge of the nose. They are two small, oblong bones that are located at the upper part of the nose, between the frontal bone and the maxilla. These bones provide support and structure to the nasal region, forming the bridge that connects the upper and lower parts of the nose.

The muscle at the tip of the chin that depresses the lower lip down one side is called the Mentalis.

The muscle at the front and sides of the neck which elevates the mandible, closes the mouth, and aids in the mastication process is the platysma. The platysma is a thin, broad muscle that covers the front of the neck and extends to the lower jaw. It helps in various movements of the jaw, including closing the mouth and elevating the mandible during chewing. The other options, sternomastoid, trapezius, and triangularis, are not directly involved in these specific functions of the jaw.
