Ganglia are called simple brains in invertebrates .
Paul Broca, a French physician and anatomist, concluded that language ability depended on the functioning of structures in a specific region of the brain now known as Broca's area.
medically high b.p is known as hypertension which may affects the brain,kidneys, and heart .
All phyla contain invertebrates. The only one that contains vertebrates is the phylum Chordata, but it also contains some invertebrates.
insects
The smallest group of invertebrates is the phylum Placozoa, which consists of a single known species, Trichoplax adhaerens. These simple, flattened organisms are composed of only a few cell layers and lack organs or distinct tissues.
The study of the structures that make up the human body, including the brain, is known as anatomy. Anatomy focuses on understanding the shapes, sizes, and locations of different body parts and how they relate to each other. It is an important field in medicine and biology for diagnosing and treating various health conditions.
Planarians belong to the group of invertebrates known as flatworms. These organisms are known for their regenerative abilities and simple anatomy, making them a common model organism in scientific research.
sponges
limbic system A group of several brain structures located under the cortex and involved in learning, emotion, memory, and motivation. Ring of structures that play a role in learning and emotional behavior. System of interconnected subcortical structures that regulates emotions and motivated behaviors, such as hunger, thirst, aggression, and sexual behavior.
The basic cause of choreic movements is overactivity of a neurotransmitter called dopamine in a set of structures deep within the brain known as the basal ganglia.
cerebellum is also known as the lesser brain
The best-known example is probably the Monarch butterfly.
