Protect Your Wellbeing After Exams
- Do prioritise rest and mental health after exams and avoid burnout during study periods.
- Reach out to colleagues and loved ones for support when you're struggling.
Hypothalamus As Autonomic Hub
- The hypothalamus is the chief regulator of autonomic function and links CNS inputs to visceral responses.
- Different hypothalamic regions mediate temperature, endocrine and sympathetic outflow.
Sympathetic Pathway Basics
- Sympathetic outflow is thoracolumbar (T1–L2/3) with short preganglionic and long postganglionic fibers.
- Postganglionic sympathetic fibres mostly release noradrenaline except key cholinergic exceptions.
