Loading… This will need to be completed and returned to Mrs Watson 5  Definition The skull or Cranium is the skeletal structure of the head that supports the face and protects the brain. The skull consists of 22 individual bones.  The Skull is made of 2 sections Neurocranium – These are the Viscerocranium – These are the Cranial Bones Facial Bones https://www.youtube.com/watch?v=FrpVzSK23Q0 En.wikipedia.org 7 Courses.lumenlearning.com  Glossary Internal – inner/inside External – outer/outside Articulate – joining/touching Medial – towards midline Ridge – Raised linear elevation Lateral – Away from midline Foramen – opening/hole to allow Anterior – Towards the front passage of blood/nerve Posterior – Towards the back Fossa – shallow depression Inferior – Underneath/below Process – large distinctive projection Superior – Above Canal – A tunnel through bone Superficial – Nearer the skin Groove – an open channel Deep – Away from the skin Tubercle – small prominent elevation Roof – top Eminence – elevation of bone Floor - Bottom Tuberosity – bulbous feature Plate – flat area of bone Margin – border/edge 8 The Neurocranium Biologydictionary.net Function of the Neurocranium -of brain Protection Attachment sites for both origin and insertion of the Muscles of Facial Expression & Muscles of mastication Framework for the cranial and orbital cavities *PAF: Protects All Functions 10  Lobes of the Brain The Cerebrum is divided into 4 lobes: Loading… each lobe is responsible for function. certain Frontal don't works completely Parietal They C independently and there Occipital is an overlap between them.

Frontal Parietal Interprets language, words Personality, behaviour, emotions Sense of touch, pain, temperature (sensory strip) Judgement, planning, problem solving Interprets signals from vision, hearing, motor, Speech, speaking, and writing (Broca’s area) sensory and memory Body movement ( motor strip) Spatial and visual perception Intelligence, concentration, self awareness 12 Psychologytoday.com  Occipital Temporal Interprets vision (colour, light and Understanding language (Wernicke's movement) area) Memory Hearing Sequencing and organization 13 Psychologytoday.com  Broca and Wernickes Areas Wernicke's area: lies in the left temporal lobe. Broca’s area: lies in the left frontal lobe Damage to this area causes Wernicke's aphasia. The If this area is damaged, one - individual may speak in long may have difficulty moving the sentences that have no meaning, tongue or facial muscles to add unnecessary words, and produce the sounds of speech. even create new words. The person can still read and They can make speech sounds, understand spoken language but however they have difficulty has difficulty in speaking and understanding speech and are writing (i.e. forming letters and therefore unaware of their words, doesn't write within mistakes. lines) – called Broca's aphasia. - 14 Biomedguide.com flow cranial bones are joined together - happens during birth.
