These bones make up our skeleton, which provides structure, support, protection, and movement to our body. The human skeleton is divided into two parts: 1. Axial Skeleton - This includes the skull, vertebral column, and ribs. 2. Appendicular Skeleton - This includes the pectoral girdle, upper limbs, pelvic girdle, and lower limbs. Out of the 206 bones, 80 are in the axial skeleton, and 126 are in the appendicular skeleton. The axial skeleton has 80 bones, and out of these, 29 bones are in the skull. The bones in the skull are connected by fibrous joints called sutures. These are immovable joints, which is why, except for the mandible (jawbone), no other bone in the skull can move. Now, let's take a closer look at the bones in the skull. The skull bones are divided into two parts: 1. Cranium 2. Facial Bones The cranium is made up of cranial bones that protect the brain. There are 8 bones in the cranium: Frontal Bone: A single bone at the front of the skull that forms the forehead. Occipital Bone: A single bone at the back of the skull. Parietal Bones: Paired bones that form the roof of the skull. Temporal Bones: Paired bones on the sides of the skull. Sphenoid Bone: A single bone shaped like a butterfly, located behind the eyes, forming the floor of the cranium. The pituitary gland is housed in this bone. Ethmoid Bone: A single bone located between the eyes and at the top of the nose, forming part of the eye socket and nasal cavity walls. Now, let's look at the facial bones that form our face: Mandible: This is the jawbone that forms the lower jaw. It is the only bone in the skull that can move. The mandible is connected to the temporal bone by the temporomandibular joint, a synovial joint that allows movement. This bone also holds the lower teeth. Maxilla: The paired bone that forms the upper jaw and the front part of the face. It also holds the upper teeth. Zygomatic Bone: Also known as the cheekbone, this paired bone forms the cheeks. Nasal Bones: Two small rectangular bones that form the upper part of the nose. They also support the cartilage of the nose. Lacrimal Bones: These are small bones located in the inner corner of the eye socket, supporting the tear ducts. Palatine Bones: Two L-shaped bones located at the back of the nasal cavity, helping to form the roof of the hard palate. Inferior Nasal Concha: A curved, paired bone found inside the nasal cavity. It helps warm and moisten the air we breathe in. Vomer: A single bone that divides the nasal cavity into two parts, helping to stabilize the structure of the nose. Hyoid Bone: A U-shaped bone located in the neck, above the larynx, that supports the tongue. In addition to these facial bones, there are also ear bones in the skull. These bones are found in the middle ear and are called the malleus, incus, and stapes. These bones help us hear sounds. The stapes is considered the smallest bone in the body. So, when we count the bones in the skull, there are 8 cranial bones, 15 facial bones, and 6 ear bones, making a total of 29 bones. #HumanSkeleton #BoneStructure #AxialSkeleton #AppendicularSkeleton #SkullBones #CranialBones #FacialBones #AnatomyBasics #BiologyLesson #BoneClassification
