QUESTION | ANSWER |
---|---|
NEURO ? | From a Nerve or the Nerves. |
NEURAL ? | Relating to a Nerve or the Central Nervous System. |
NEUROLOGY ? | Study of Nerve Systems. |
CEREBRAL ? | Of the BRAIN. |
CEREBRAL HEMISPHERE ? | Each of the 2 halves of the Vertabrate Cerebrum. |
CEREBRUM ? | The Principal part of the Brain, located in the Front Area of the Skull, contains the THALAMUS & HYPERTHALAMUS. |
CEREBRUM, Function ? | Intergrates Complex Sensory & Neural Functions |
CEREBELLUM ? | The part of the Bat the Lower Back of the Skull, Underneath the Cerebrum. |
CEREBELLUM, Function ? | Coordinates & Regulates MUSCULAR Activity |
THALAMUS ? | Either of the 2 Masses of Grey Matter in the Forebrain. |
THALAMUS, Function ? | Recieves most of the Sensory Impulses from the Body & Distributes them to Special Sence Areas |
HYPOTHALAMUS ? | The Region of the Brain which Controls BODY TEMPERATURE, HUNGER, THIRST, & EMOTIONAL CHANGES. |
MEDULLA OBLONGATA ? | The Continuation of the SPINAL CORD within the Skull, forming the Lowest Part of the Brain Stem. |
MEDULLA OBLONGATA, Vital Centres ? | CARDIOVASCULAR Centre, RESPIRATORY Centre, REFLEX Centres of Vomiting, Coughing, Sneezing & Swallowing. |
MEDULLA OBLONGATA, How Long ? | About 2.5cm Long. |
MENINGES ? | The 3 MEMBRANES Lying Between the SKULL and the BRAIN. |
MENINGES, Consisting Of ? | 2 Layers of DURA MATER, 1 ARACHNOID MATTER & 1 PIA MATTER. |
MENINGES, Function ? | Protect the BRAIN & SPINAL CORD, Absorb Cerebro Spinal Fluid & Supply Blood to Surface of Brain. |
NERVE ? | A Fibre or Bundle of Fibres. |
NERVE, Function ? | Transmits Impulses of Sensation or Motion Between Brain or Spinal Cord & other parts of the Body. |
NEURONE ? | A Scell Transmitting Nerve Impulses. |
SPINAL CORD ? | Cylindrical Structure of the Central Nervous System Enclosed in the Spine. |
VAGUS ? (vay-gus) | Either of the 10th Pair of Cranial Nerves, with Branches to the Heart, Lungs & Viscera. |
CEREBRAL PALSY is ? | A Condition Marked by Weakness & Impaired Coordination of the Limbs. |
NEURALGIA is ? | An Intense Intermittent Pain Along the Course of a Nerve. |
NEUROPATHY is ? | A DISEASE or Dysfunction of 1 or more Peripheral Nerves. |
(Q) Describe the Structure of the SPINAL CORD ? | A cylindrical Elongated part of the Central Nervous, Situated within the Vertebral Canal, Completely Surrounded by the Spinal Meninges & Cerebro Spinal Fluid, In an Adult Extends from Foramen Magnum, Atlas to 1st/2nd Lumbar Verebra. |
How Long is the SPINAL CORD ? | It is About 45cm Long. |
What is the SPINAL CORD Composed of ? | GREY MATTER in the Centre & Surrounded by WHITE |
How many SPINAL NERVES are there ? | 31 Pairs. |
(Q) Describe the Function of the SPINAL CORD ? (1 of 3)(N,C,c,c) | Nervous Tissue Link between Brain & rest of Body. Conveys Impulses from Brain to Various Crtans & rest of body. |
(Q) Describe the Function of the SPINAL CORD ?(2 of 3) (n,c,C,c) | CONVEYS Impulses from spinal Nerves which leave at various levels to serve the Structures they Supply. |
(Q) Describe the Function of thr SPINAL CORD ? (3 of 3) (n,c,c,C) | A CENTRE of Reflex Action, Spinal Reflexes Act without the Brain & are Supported by a Network of Motor & Sensory Nerves at Same or Different Levels of the Cord. |
(Q) Describe the Function of the MEDULLA OBLONGATA ? (1 of 2) | 1. Link Between Brain & Spinal Cord, 2. Contains Vital Centres, RESPIRATION, CARDIAL & VASO MOTOR, 3. Allows Motor Fibres to Cross Over, Thus Right Side of Brain Controls Left Side of Body. |
(Q) Describe the Function of the MEDULLA OBLONGATA ? (2 of 2) | 4. Contains Reflex Centres, Controlling Food & Air Passages & Reflex Actions of Swallowing, Vomiting, Coughing & Sneezing. |
