Dear student

Answer is White matter.
Medulla Oblongata is the structure found in the human brain which perform autonomic functions (that are not in human control) like breathing, respiration, heart Beat. It is also involved in body secretion, reflexes, swallowing, coughing and sneezing actions.
The central portion of the medulla oblongata contains gray matter, while the outer portions consist of white matter. The posterior white matter contains the fasiculus gracilis.
