BRAIN MENINGES - Dura Mater 4 PARTS - Arachnoid Mater - Cerebrum - Pia Mater - Cerebellum - Diencephalon - Brainstem LOBES OF THE BRAIN  BRAINSTEM LOBES FUNCTIONS Frontal motor and intelligence -behavior and emotions - executive functioning - Language production Parietal - sensory integ., perceptual fxn Temporal - hearing - speech and language comprehension Occipital for vision DIENCEPHALON SKELETAL SYSTEM BONE ANATOMY Femur Thigh Bone Tibia and Fibula Leg Bone  Total of 206 bones in a average human skeleton  2 Major Divisions: Patella Knee Cap  Axial Skeleton – 80 bones  Appendicular Skeleton – 126 bones Tarsals, Metatarsals, Ankle and Foot Phalanges JOINTS  Is a place where 2-3 bones come together Bone (Upper extremity) Based on the Degree Based on Function Example Sternum Dagger Bone of Motion Connective Tissue Synarthrosis Fibrous Joints Non movable Syndesmosis, Scapula Wing Bone Sutures Clavicle Collar Bone Gomphosis Humerus Arm Bone Amphiarthrosis Cartilaginous Joints Less movable Synchondrosis, Radius and Ulna Forearm Bone Symphysis Carpals, Metacarpals, Wrist and Hand Diarthrosis Synovial Joints Freely movable Phalanges Bone (Lower Extremity) Pelvic Girdle Hip Bone Muscular System Braincase Facial Bones Diathrodial Joints Muscles of Facial Expressions – Paired Paired Parietal Maxilla Innervated by the Facial Nerve – Temporal Zygomatic Glenohumeral Joint Shoulder Joint Cranial Nerve 7 Unpaired Lacrimal Temporomandibular Joint Jaw Joint Frontal Nasal Humeroulnar Joint Elbow Joint Occipital Palatine Radiocarpal Joint Wrist Joint Sphenoid - keystone Inferior Nasal Concha Interphalangeal Joint Finger Joint Ethmoid Unpaired Acetabulofemoral Joint Hip Joint Mandible Tibiofemoral Joint Knee Joint Vomer Talocrural Joint Ankle Joint Muscle Action Occipitofrontalis/Frontalis Raising your eyebrows Corrugator Supercilli Draws your eyebrows together Nasalis Wrinkling of nose Orbicularis Oculi Forceful closing of the eye Risorius Laughing with your mouth open Zygomaticus Minor/Major Smiling Levator Labii Superioris Elevates upper lip Depressor Labii Inferioris Protrudes lower lip Buccinator Blowing Orbicularis Oris Kissing/sucking Platysma Disgust levator palpebrae superioris elevates the upper eyelid depressor anguli oris depress the corners of the mouth Muscles of Mastication – innervated by Trigeminal Nerve – Cranial Nerve 5 Trigeminal Nerve – largest cranial Nerve Branches of Trigeminal N - Ophthalmic Branch - Maxillary Branch - Mandibular Branch Muscle Action Masseter Mouth Closing Medial Pterygoid Mouth Closing Temporalis Mouth Closing Lateral Pterygoid Mouth Opening Muscles of the Neck ` SupraHyoid Muscles Digastric, Mylohyoid, Stylohyoid, Geniohyoid Infrahyoid Muscles Omohyoid, Thyrohyoid, Sternothyroid, Sternohyoid ExtraOccular Muscles of the Eye Muscles of the Tongue  Genioglossus  downwards and forward  Styloglossus  Upward and backwards  Hyoglossus  Downwards and flatten  Palatoglossus  Elevates back of the tongue
