The Body of Christ has elbows and knees just like any body would have. They are the joints that connect the body, that mobilize the seperate parts they are connected too. When a connector anointing joins two different functions together in the Body of  Christ, they themselves, enter into that function’s heavenly reward, for being the (connecting tissue of a work) in the righteous acts of the saints. 

1 Corinthians 12:27 Now you are the body of Christ, and each of you are a member of it.
