    No. 98-60126
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Nov. 6, 1998.
    Gary R. Parvin, Coffeeville, MS, Chantal J. Harrington, Sarah Harriet Bohr, Jacksonville, FL, for Plaintiff-Appellant.
    Scott E. Heffington, Dennis R. Williams, Mary Ann Sloan, Joseph P. Palermo, III, Social Security Administration, Office of the General Counsel, Atlanta, GA, James William Warren, Jr., Calvin D. Buchanan, Oxford, MS, for Defendant-Appellee.
    Before POLITZ, Chief Judge, and STEWART and PARKER, Circuit Judges.
   PER CURIAM:

Juatassa Sims appeals the district court’s affirmance of the Commissioner’s denial of her application for disability insurance benefits, contending that the administrative law judge: (1) failed to afford proper weight to a psychologist’s opinion that she was severely depressed; (2) improperly excluded certain of her impairments in assessing her residual function capacity; and (3) should have ordered a consultative examination to assess her mental impairments. We affirm.

We lack jurisdiction to review Sims’s second and third contentions because they were not raised before the Appeals Council. The first contention is without merit because the ALJ is entitled and expected to determine the credibility of medical experts and to weigh their opinions accordingly. Concluding that the findings of the ALJ are supported by substantial evidence, the judgment appealed is AFFIRMED.
