Answer:
Maintenance of postural equilibrium is an integrated process requiring optimal muscular balance, joint dynamics, and neuromuscular efficiency using visual, vestibular, and proprioceptive inputs.
Explanation:
Maintaining postural equilibrium involves multiple parts of the body, and can be divided in two levels of control: the first one being on the brainstem, the cerebellum and the spinal cord; and the second one including cortical areas that participate in multisensory integration and control as well as the basal ganglia located in the cerebrum.
Answer:
Muscles are stimulated by electricity. The effect depends on the intensity of the current and the type of muscle it travels through.
The victim may be unable to let go of the source of the current, making the duration of the contact longer and increasing the severity of the shock.
When a current above 10 mA travels through extensor muscles, it causes a violent spasm. If the muscles affected are the hip extensors that lengthen the limbs away from the body, the victim may be propelled, sometimes many metres away!
Muscles, ligaments and tendons may tear as a result of the sudden contraction caused by an electric shock. Tissue can also be burned if the shock is lasting or the current is high.planation:
The prey population decreases when the preadator population increases.
