The categories are:

Specific phobias: Fear of particular objects or situations that results in anxiety and avoidance. May lead to panic attacks if exposed to feared stimulus or in anticipation of encounter. A specific phobia may be further subdivided into five categories: animal, natural environment, situational, blood-injection-injury, and other. Agoraphobia: a generalized fear of leaving home or a small familiar safe area and of possible panic attacks that might follow. Various specific phobias may also cause it, such as fear of open spaces, social embarrassment (social agoraphobia), fear of contamination (fear of germs, possibly complicated by obsessive–compulsive disorder) or PTSD (post-traumatic stress disorder) related to a trauma that occurred outdoors. Social anxiety disorder (SAD), also known as social phobia, is when the situation is feared out of a worrying about others judging them. Performance only is a subtype of social anxiety disorder Phobias vary in severity among individuals. Some individuals can avoid the subject and experience relatively mild anxiety over that fear. Others experience full-fledged panic attacks with all the associated impairing symptoms. Most individuals understand that their fear is irrational but cannot override their panic response. These individuals often report dizziness, loss of bladder or bowel control, tachypnea, feelings of pain, and shortness of breath. Causes
There are multiple theories about how phobias develop and likely occur due to a combination of environmental and genetic factors. The degree to whether environment or genetic influences have a more significant role varies by condition, with social anxiety disorder and agoraphobia having around a 50% heritability rate.
The epoophoron or epoöphoron (also called organ of Rosenmüller or the parovarium) is a remnant of the mesonephric tubules that can be found  next to the ovary and fallopian tube. Anatomy
It may contain 10–15 transverse small ducts or tubules that lead to the Gartner’s duct (also longitudinal duct of epoophoron) that represents the caudal remnant of the mesonephric duct and  passes through the broad ligament and the lateral wall of the cervix and vagina. The epoophoron is a homologue to the epididymis in the male. While the epoophoron is located in the lateral portion of the mesosalpinx and mesovarium, the paroophoron (residual remnant of that part of the mesonephric duct that forms the paradidymis in the male) lies more medially in the mesosalpinx. Histology
It has a unique histological profile. Clinical significance
Clinically the organ may give rise to a local paraovarian cyst or adenoma. See also
