Multiple Choice

Q1: When lifting a heavy load, the spinal reflex that is called upon is:

• The myotatic reflex

• The plantar skin reflex

• The inverse myotatic reflex

• The stylo-radial reflex

• The naso-palpebral reflex

Multiple Select

Q2: This reflex

• is monosynaptic.

• has as receptor sensory neuronal fibers located at the level of the tendons

• inhibits the α-motor neuron

• induces relaxation of the agonist muscle

• can be modulated by supramedullary afferents

Multiple Select

Q1: This attitude corresponds to:

• An exteroceptive reflex

• A polysynaptic reflex

• A flexion (withdrawal) of the injured limb (attacked).

• An extension of the contralateral limb to stabilize the body (avoid falling).

• Not a reflex

Multiple Select

Q2: This reflex allows:

• On the homolateral side, the withdrawal of the attacked limb by the contraction of the flexors.

• On the homolateral side, the contraction of the extensors

• On the contralateral side, the contraction of the extensors

• On the contralateral side, the contraction of the flexors

Multiple Select

Q3: This reflex

• involves several spinal cord levels

• involves only one spinal stage

• involves the proprio-spinal bundles

• originates in the nocereceptors of the foot

• involves several interneurons at a given level of the spinal cord

Multiple Select

Q1: this withdrawal reflex

• Allows you to move your hand away from the source of aggression

• It is a monosynaptic reflex

• Its starting point is a noci-receptor

• It can last for seconds after the end of the stimulation

Multiple Select

Q2: the post discharge period

• characterizes the nociceptive reflexes.

• is attributed to the presence of reverberating circuits

• is of independent duration of the intensity of the stimulus.

• is intensity dependent on the intensity of the stimulus

• is a protective mechanism
