Differentiate between kyphosis and lordosis
Kyphosis: outward curvature
Lordosis: inward curvature
what is scoliosis?
Abnormal lateral, S-haped curvature of the spine
what is the surface landmark for T3?
At the level of the base of the spine of the scapula
what is the surface landmark for T7?
At the level of the inferior angle (tip) of the scapula
what is the surface landmark for L4/5?
at the level of a line drawn between the tips of the iliac crest
where does spinal cord terminate?
L1/2
What movements occur at the cervical spinal region?
Flexion and extension

where are upper motor neurons found and what do they do?
Found in motor region of cerebral cortex and brainstem.
Transmits impulses from the brain to synapses of lower motor neurons
where are LOWER motor neurons found and what do they do?
Found in brainstem and spinal cord.
Motor neuron that transmits nerve impulses from upper motor neurons to muscles
