Vocational education is education that prepares people to work as a technician or to take up employment in a skilled craft or trade as a tradesperson or artisan. Vocational education is sometimes referred to as career and technical education.

As you have not provided the state of yours so it's can't be concluded in which vocational you can go. But in general perspective there are no specialized courses for you after BSc Physiology but you can always go for other courses.

I hope my answer helps. All the very best for your future endeavors!
