When ligand gated ion channels open in the postsynaptic neuron, and lead to an inhibitory postsynaptic potential (IPSP), this is a   

The  gastrocnemius and soleus insert by a common  Achilles tendon on which bone of the foot?     

In myelinated axons because the voltage-gated sodium channels are only located at the nodes of Ranvier; therefore the nerve impulse jumps from node to node, making saltatory conduction possible.

Opening of which ion channels triggers the generation and conduction of the long distance action potentials ( nerve impulses) along the axons?    

During which period of a ‘twitch’ contractions are the Ca++ pumped back into the sarcoplasmic reticulum for storage?  

The part of a neuron that conducts nerve impulses away from its cell body is called a(n) ________.  

Skeletal muscle cells have all of the following microscopic features except:  

A contraction in which the muscle tension builds up, but the muscle does not change length and no movement occurs is   

Muscle tone is the constant, partial state of muscle contraction which does not produce active movements

Smooth muscle cells have actin & myosin filaments and sarcomeres.
