1 (pair work). Answer questions after reading the text below.

True or False. Correct the false sentences. Use the the text below.

A___The medulla controls the autonomic system.

B___Autonomic reflexes are more specific.

C___Somatic reflexes are more specific.

2 (individual work). Answer the questions using the text below.

1. What are differences between autonomic and somatic reflexes?
2. What are the functions of medulla in terms of autonomic control?

Example of autonomic reflex: “The pupillary light reflex begins when light hits the retina and causes a signal to travel along the optic nerve. This is visual sensation, because this reflex is simply sharing the special sense pathway. Bright light hitting the retina leads to the parasympathetic response, through the eye nerve, which stimulates the circular fibres of the iris to contract and constrict the pupil. When light hits the retina in one eye, both pupils contract. When that light is removed, both pupils dilate again back to the resting position. When the stimulus is presented to only one eye, the response is to both eyes”. The same is not true for somatic reflexes. If you touch a hot radiator, you only pull that arm back, not both. Central control of autonomic reflexes is different than for somatic reflexes. The hypothalamus, along with other CNS locations, controls the autonomic system.The medulla (продолговатый мозг) contains cells referred to as the cardiovascular centre, which controls the smooth and cardiac muscle of the cardiovascular system through autonomic connections.
