Question

Lateral Corticospinal tract carries information regarding   ____________________movement that is ________________________________ (Ex. you can move your fingers independently as opposed to as one unit with the hand).

Receptors on the Sacrolemma opens _________________channels when ATCH binds and an action potential travels down the ____________________causing Ca++ channels to open.

Ca++ binds to _______________________to remove the block of the binding sites.

Answer 1

Ans . Lateral Corticospinal tract carries information regarding Voluntary movement that is movements of contralateral limbs .

• Receptors on the Sarcolemma opens Ligand- gated ion channels when ATCH binds and an action potential travels down the axon of motor neuron causing Ca++ channels to open.
• Ca++ binds to troponin  to remove the block of the binding sites.

The sarcolemma is the plasma membrane of muscle cell and is surrounded by basement membrane and endomysial connective tissue.

As soon as the neurotransmitter reaches the sarcolemma it binds to receptors on a ligand-gated ion channel , these receptors specific for ATCH.
