The Nervous System

QUESTIONANSWER
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.
