No, the amygdala is not the entire human reptilian brain. However, the amygdala is a part of the brain's limbic system and plays a role in processing emotions, particularly fear and aggression. The reptilian brain refers to the brainstem and cerebellum, which are involved in basic survival functions.
Cephalization has great importance in the evolution. It is considered as great achivement by the animals. Besides its advantages, it has some disadvantages too. The disadvantages of cephalization are 1. The animal cann't see what happening behind its head. 2. Head can be moved upto 180 degree angle in most of the animals including humans. But it is not true in case of birds.
The lack of cephalization in sea stars is not a disadvantage because they possess decentralized nerve nets that allow them to coordinate movement and respond to their environment effectively. Their radial symmetry also aids in this coordination. Additionally, their specialized tube feet help them to navigate and capture prey without the need for centralized brain control.
Complex animals tend to have specialized cells, bilateral symmetry, cephalization, and a body cavity.
The brain is referred to as reptilian because it consists of structures that are evolutionarily older and are similar to those found in reptiles. These structures are responsible for basic survival functions such as breathing, heart rate, and fight or flight responses.
Cephalization
A hydra does not have cephalization.
The cephalization of a mollusca could possibly describe the arrangement of neurons in the front end of the animal.
Cephalization means formation of a head. Cnidarians have no head, so no.
Animals with cephalization respond more quickly and in more complex ways.
Amphibious
Yes. They have extensive cephalization. They have a brain and eyes.
they do not
nervis system
A sponge.
Cephalization refers to the gathering of neural tissue towards the anterior or posterior for means of central control. In arthropods, cephalization has formed the brain in the head of the animal, usually consisting of the first three ganglia of the paired nerve cords.
A suffix that could be added to "reptilian" is "istic," resulting in "reptilianistic."
