A.1.1.1 Inter-system communication (part 1)

The somatic nervous systen controls what type of movements?

Homeostasis is the term used to describe the...

• Build up of lactic acid

• equilibrium in the body's internal environment.

• Muscle contractions

• Specialised receptor cells

Stressful environments such as extreme heat, humidity, cold, or high altitude can disrupt homeostasis. In response, the body makes adjustments to restore balance. 

For example, in hot conditions, the body sweats to cool down, while in cold conditions, it shivers to generate _ _ _ _

What are the main functions of the nervous system?

• Communication

• Coordination

• Emotion

• Interaction

The two parts of the motor nervous system are...

• Somatic

• CNS

• Autonomic

• Sympatheitc

The peripheral nervous system is divided into:

• Autonomic

• Sensory (afferent)

• Somatic

• Motor (efferent)

What nervous system does this describe? Activities the “fight-or -flight response”. Increases bodily function e.g. breathing rate.

An example is the increasing of blood flow during exercise through vasodilation and vasoconstriction.  Helps with thermoregulation.

The somatic and autonomic nervous system fall under the _ _ _ _ _ nerves

It carries out processes such as digestion, urination, glandular secretion (fluid released by glands) and conservation of energy (slows the bodily functions down e.g. HR)

What is vasocontriction?

• Increase in breathing rate

• Widening of the blood vessels

• Narrowing of the blood vessels

• Sweat gland production
