Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
Answer:
Skeletal muscles fibre are classified base on how the produce energy.
Explanation:
Skeletal muscles fibres consist of bundles of cells that form muscles which contain myobrills.
Skeletal muscles are classified based on how the produce energy;
Type 1 or slow pitch muscle fibres are more efficient and last for a long period of time. They are use for postural maintenance or endurance. It use aerobic respiration to produce energy or ATP.
Type 11 or fast twitch muscle fibres use anaerobic respiration and are for short speed and fatigue more easily than type 1.
