Junior Med Tech Nerv
Nervous System
| Question | Answer |
|---|---|
| Directs sensory impulse to the cerebrum | Thalmus |
| Regulates and controls the autonomic system | Hypothalmus |
| Resonsible for certain reflexes: chewing, tasting, saliva and assist with respiration | PONS |
| Lowest part of brain stem | Medulla Oblongata |
| Regulates heart beat, respiration, swallowing, coughing | Medulla Oblongata |
| Located below the cerebrum | Mid brain |
| membranes that cover and protect the brain and spinal cord | Meninges |
| thick, touch outer membrane of the meninges | Dura mater |
| Middle layer of the meninges, delicate and weblike | arachnoid |
| inner most layer of the meninges | pia mater |
| The four hollow spaces of the brain filled with CSF | The Ventricles |
| Fluid that circulates between the ventricles of the brain and spinal cord | Cerebral Spinal Fluid (CSF) |
| Serves as a shock absorber to protect the brain | CSF |
| Consists of somatic and autonomic nervous system | Peripheral Nervous System |
| Maintains involuntary function of the body, allows body to react in times of emergency | Autonomic Nervous System |
| Fight or flight | Sympathetic Nervous System |
| Rest and Digest | Parasympathetic Nervous System |
| Associated with voluntary control of the body | Somatic Nervous System |
| Basic structural unit of the nervous system | Neuron |
| Receives information(part of neuron) | Dendrite |
| Transmits information (part of neuron) | Axon terminals |
| Located at the end of each axon, allow impulses to transfer from one neuron to the next | Neurotransmitters |
| sensory nerves, carry information to the brain | Afferent |
| Motor nerves, carry messages from the brain and spinal cord to the muscles and glands | Efferent |
| Nerves carry both sensory and motor messges | associative |
| Space between two neurons | synapse |
| Part of the brain responsible for balance, posture and coordination | Cerebellum |
| Part of the brain responsible for hearing, speech and memory | temporal lobe |
| Part of the brain responsible for pain, heat,touch, motor and sensory | Parietal lobe |
| Part of the brain responsible for emotions, personality, intellect and speech | Frontal lobe |
| Part of the brain responsible for visiual association and vision reception | Occipital Lobe |
| Carries nutrients to some parts of the brain and spinal cord | CSF |
| Continues from Medulla Oblongata to 1-2nd lumbar vertebrae | Spinal Cord |
