KEY TERMS

• Bradykinsia- slowness of motion
• Ridigity- stiffnesss of joints
• Afferent - neurons that send Info. to the CNS
• Efferent- neurons that recive from cns and carry out action
• Tremors- shaking

Sensory input – stimuli recieve and send message to the brain or spinal cord. Integration – interneurons in the brain or spinal cord process and interpret the messages from the sensory neurons, and relay the massage back to body parts. Motor output – Receive the message from interneuron and produce a response at a muscle or a gland

• Sensory input – sensory or afferent neutron detect internal or external changes ( stimuli ) and send the message to the brain or spinal cord.
• Motor output – motor or efferent neurons receive the message from interneuron and produce a response at the effector organ ( a muscle or a gland).
• Integration – interneurons in the brain or spinal cord process and interpret the message from the sensory neurons, and relay the massage back to body parts

PARKINSONS

• Malfunction and death of neurons in the brain
• Symptoms:
• Tremors,bradykinsia,rigdity,imbalance coordination
• Treatmeant:
• There are medications to help but non can reverse the effects

MENEGITIS

• Meningitis usually results from a viral infection, but the cause may also be a bacterial infection
• Signs: SEVER HEADACHE,HIGH FEVER, STIFF NECK, VOMITTING,SEIZERS
• Causes: hearing loss, seizers, memory ,brain damage
