Answer:
Answer is thoracic region.
Explanation:
Paravertebral ganglia are subdivision of peripheral sympathetic nervous system , which is one of the part of autonomic nervous system found in mammals. Its components are superior and inferior mesenteric ganglia and celiac.
The spinal nerves are peripheral nerves arising from the spinal cord. These spinal nerves are altogether 31 pairs. 8 in cervical, 12 in thoracic, 5 lumbar, 5 in sacral, and 1 in caudal.
There are two types of spinal nerves composed of the sensory and motor fibres.
Answer:
the difference is that its bigger
Explanation:

Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.
