What cells produce hormones that are released by the Hypotharamus gland?

The hypothalamus itself produces hormones that are released directly into the bloodstream. These hormones include releasing and inhibiting hormones, which regulate the function of the pituitary gland. Specific neurosecretory cells in the hypothalamus, such as paraventricular and supraoptic neurons, synthesize hormones like oxytocin and vasopressin (antidiuretic hormone) that are stored and released from the posterior pituitary.
