For a finite group K, let Cent(K) denote the set of centralizers of single elements of K. Let
G be the extra-special group of order p^(2n+1) where p is a prime and n ≥ 1. Here we obtain
│Cent(G)│ and as an application we show that │Cent(H)│ ≤ │Cent(G)│ for all groups H of order
p^(2n+1). Also we give some information about groups having maximum number of centralizers
among all groups of order p^(2n+1).
