Sea Turtle Anatomy:

...

- Components

- The nervous system of the sea turtle is composed of the brain, nerves and spinal cord.

- In addition, specialized cells called neurons are the signal transmitters throughout the system.

- The forebrain extends from the nose to the posterior cerebrum.

- The spinal cord of the turtle goes down it's back and is protected by the carapace vertebrae.

- Only the optic and olfactory nerves are still attached to the thread.

- Through the spinal cord the information is carried to and from the brain.

- Fun facts

- Sea turtles can even smell underwater.

- Turtles have all the same senses as most organisms but the sense of smell is more advanced.

- Homeostasis and relations to other systems

- In order to maintain homeostasis, the nervous system controls and regulates other parts of the body.

- The nervous system works pretty much with all the other system in order to keep them working properly and sending directions on what to do.

Circulatory System:

Sea Turtles circulatory system includes the heart, arteries, veins, and lymphatic vessels and as we all know the heart that contains four chambers and it has the function of pumping blood throughout the sea turtles body. However, getting further, the circulatory system is divided into three parts that are all equally important to maintain homeostasis, the heart, blood and blood vessels (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).

In the systemic, arteries like human arteries are composed thick walls of muscle and they serve the function of carrying oxygenated blood from the heart into the rest of the body in the other hand veins that are also found in sea turtles have a thinner wall of muscle and they carry deoxygenated blood back into the heart. The sea turtles also have lymphatic vessels that surround the arteries and veins they are minuscule and normally can’t be photographed and they serve the function of transporting tissue fluid from outside the circulatory system into the blood.

The sea turtles cardiovascular system contains a three chambered heart with a left auricle, the right auricle and the ventricle and the system also contains blood and blood vessels. These parts all work work together because as the heart receives oxygenated blood from the pulmonary circulation it is able to pump that oxygenated blood through the sea turtles body in a process called systemic circulation.

Last but not least the pulmonary part more in detail helps send deoxygenated blood through the heart’s chambers into the pulmonary artery so the heart can the pump oxygenated blood throughout the the sea turtles body to maintain homeostasis. Without the circulatory system sea turtles would be able to fight disease and be able to maintain a stable environment in the internal body of a sea turtle (homeostasis).

Locomotion System:

A sea turtle's skeleton is divided into two main parts the endoskeleton and exoskeleton. Mainly the endoskeleton is all the internal bones and the exoskeleton is the sea turtle's shell. The endoskeleton is divided up into two main sections the axial skeleton and the appendicular skeleton. The axial part contains the skull and what are called the cervical and thoracic vertebrae. The appendicular part basically contains all the other bones in the skeleton like the Humerus, Tibia, Radius, Tarsals, Ulna, Metatarsals, Carpals, Phalanges just to name a few and they all work together along with muscles, joints and tendons in order for a sea turtle to move around both on land and on water. Coming back to the axial part the skull like all skulls normally serves the purpose of protecting the brain and other parts of the head and the vertebrae work along with the nervous system like a highway of information and in all sea turtles except the leatherback the spine is attached to the carapace.

Sea turtle muscles are also very important like the heart, and the ones found in the fins in order for sea turtles to swim under water and for the females to be able to dig the nest in land as well as just move around. The tendons and joints although they may seem small they allow the bones to move easily and basically connect the muscles to the bones.

The locomotion system of a sea turtle helps maintain homeostasis in many ways, bones generate red blood cells that transport nutrients and oxygen through a sea turtle's body and the muscular system works along with other systems to regulate body
