2 Objectives Be ready to locate and identify the bones and the major features of the bones that include the skull Be able to describe the distinguishing options between men and women in the options of the skull

3 Anterior View of the Skull

4 Orbit of the Eye

5 Lateral View of the Skull

6 inferior View of the Skull

7 The Human Skull Consists of 22 bones that are firmly interlocked along sutures, except for the lower jaw Eight of these bones make up the cranium Fourteen of those bones make up the facial skeleton The mandible or decrease jawbone is movable and hooked up to the cranium through ligaments Some facial and cranial bones in combination shape the orbit of the eye

8 The Cranium Encloses and protects the brainIts surface provides attachments for muscles that allow chewing and head movements Some cranial bones contain air-filled cavities known as paranasal sinuses

9 The Sinuses These cavities are coated with mucous membranes and are hooked up by passageways to the nasal cavity They cut back the weight of the skull Serve as resonant sound chambers through expanding the intensity of the voice

10 Paranasal Sinuses

11 Bones of the Cranium Frontal bone Parietal bone (2) Occipital boneTemporal bone (2) Sphenoid bone Ethmoid bone

12 Frontal bone Forms the anterior portion of the cranium above the eyesMakes up the forehead, the roof of the nasal hollow space and the roofs of the orbits (sockets) of the eyes On the higher margin of each orbit, the frontal bone is marked by means of a supraorbital foramen (or supraorbital notch) Through here blood vessels and nerve move to the tissues of the forehead Within the frontal bone, are the two frontal sinuses The frontal bone is a unmarried bone in adults however develops in two portions and is not utterly fused till 5-6 years of age

13 Parietal bone Locate on every aspect of the cranium just in the back of the frontal bone Shaped like a curve plate and has four borders Together, the parietal bones form the bulging sides and roof of the cranium They are fused at the midline along the coronal suture

14 Occipital bone Joins the parietal bones alongside the lambdoid sutureForms the back of the skull and the base of the cranium A large opening on its decrease floor is the foramen magnum This is the place the inferior part of the brain stem connects with the spinal cord Rounded processes called occipital condyles, located on every side of the foramen magnum, articulate with the first vertebra (atlas) of the vertebral column

15 Temporal bone Located on every side of the skullIt joins the parietal bone alongside a squamous suture Forms part of the aspect and base of the cranium Located close to the inferior margin is an opening, the exterior acoustic meatus, which leads inward to portions of the ear The temporal bones space the interior ear constructions They even have depressions known as the mandibular fossae (glenoid fossae) that articulate with condyles of the mandible

16 Projections of the Temporal boneBelow each exterior acoustic meatus are two projections: A rounded mastoid process and a long, pointed styloid process The mastoid process supplies an attachment for positive muscle mass of the neck The styloid process anchors muscle tissues associated with the tongue and pharynx The zygomatic procedure projects anteriorly from the temporal bone It joins the temporal procedure of the zygomatic bone and is helping shape the prominence of the cheek referred to as the zygomatic arch

17 Openings close to the Temporal boneThe carotid canal, which transmits the inside carotid artery is positioned near the mastoid process Between the temporal and occipital bones is an opening known as the jugular foramen, which comprises the internal jugular vein

18 Sphenoid bone Is wedged between several other bones in the anterior portion of the cranium Consists of a central part and two wing-like structures that extend laterally towards every aspect of the cranium Helps to shape the base of the cranium, the aspects of the cranium, and the flooring and aspects of the orbits A portion of the sphenoid bone indents to form the saddle-shaped sella turcica (Turk's saddle) The pituitary gland lies right here There are also two sphenoidal sinuses within

19 Ethmoid bone Is positioned in front of the sphenoid boneConsists of two masses, one on every aspect of the nasal cavity which are joined horizontally via thin cribriform plates These plates form part of the roof of the nasal cavity and nerves related to the sense of smell cross thru tiny openings known as olfactory foramina Portions of this bone also form sections of the cranial floor, orbital walls, and nasal hollow space walls It incorporates ethmoidal sinuses, who warm and clear out the air that enters the respiration machine

20 Other Structures Connected to the Ethmoid boneA perpendicular plate initiatives downward in the midline from the cribriform plates to shape most of the nasal septum Delicate, scroll-shaped plates known as the superior nasal concha and the middle nasal concha venture inward towards the perpendicular plate Projecting upward into the cranial hollow space between the cribriform plates is a triangular process called the crista galli (cock's comb)
