Endocrine System Hormones Quiz

Autonomic Nervous System (ANS)

• The main function of the ANS is to regulate involuntary actions, such as heart rate, breathing, and digestion.

Nervous System

• The peripheral nervous system (PNS) includes nerves originating from peripheral nerves and spinal nerves.
• The nervous system consists of specialized tissues responsible for providing control and coordination in animals.
• The Central Nervous System (CNS) integrates and processes information from sensory receptors and sends responses to effector organs.
• The nervous system regulates voluntary muscular activities through the CNS.

Nerve Impulses

• The unit of the nervous system responsible for transmitting nerve impulses is the neuron.
• Neurons do not divide after their formation.
• The role of synapses is to facilitate the transmission of nerve impulses between neurons.
• A nerve impulse is a wave of electrical activity that travels along the length of a neuron.

Hormones

• The 3F hormone (not specified in the text) has a main function that is not mentioned.
• Progesterone is responsible for stimulating the uterine lining for embryo implantation.

Plant Growth and Movement

• Plants respond to external stimuli through growth, movement, or tropism.
• Tendrils in climber plants exhibit tropistic movement dependent on growth.
• Hormone secretion helps regulate blood calcium levels when they are decreased.
• Progesterone and estrogen have a main role in regulating the female reproductive cycle.
• Abscisic Acid (ABA) is responsible for preventing premature leaf fall.
• Ethylene reverses the growth-promoting effects of Auxin and Gibberellins.
• Auxin stimulates cell division and lateral branching.
• Gibberellins promote the elongation of roots and stems but cause lateral expansion.
• Tropism is the directional growth or movement of a plant organ in response to external stimuli.
• Phototropism is characterized by the movement of a plant part in response to light.
• Geotropism causes growth in plants in the direction of gravity.
• Chemotropism is the growth of a part of a plant in response to a chemical stimulus.
• Auxins are synthesized at the shoot tip of the plant body.
• Plant hormones help in growth, development, and response to the environment.
