Parkinson's Disease

Damage to the substantia nigra causes a decrease in the neurotransmitter dopamine. This causes a gradual, generalized increase in muscle tone, which is the main syptom of


Which of the following is not one of the special senses

Central adaptation refers to

Fast Pain

Which of the following is sometimes called "prickling pain"


Endorphins can reduce perception of sensations initiated by

Requires the coordinated activity of several regions of the brain

Complex motor activities such as riding a bicycle

Upper Motor

Motor neurons whose cell bodies are within the spinal cord are called__________ neurons


In order for a sensation to become a perception

Receptor Specificity

Gustatory receptors are sensitive to dissolved chemicals but insensitive to light. This is due to


Peripheral adaptaion _________ the number of action potentials that reach the CNS


Receptors that monitor the position of joints belong to the category called


Mechanoreceptors that respond to changes in blood pressure

Ventrio Lateral, Medullary Surface, Sensitive to pH

Chemoreceptors are loc

posterior spinocerebellar

The spinal tract that carries sensation from the proprioceptors to the CNS is the

fosciulus gracilis

Which ascending tract carried the sensation for fine touch and vibration

anterior spinothalmic

The spinal tract that relays information concerning pain and temp to the CNS is the

spinothalmic pathway, posterior column pathway, spinocerebellar pathway

Each of the following is an ascending tract in the spinal cord
