Quick Answer: The Study Of The Comparative Anatomy Of The Vertebrate Brain Demonstrates What?

What is comparative vertebrate anatomy?

Comparative vertebrate anatomy – the study of structure, of the function of structure, & of the range of variation in structure & function among vertebrates: Kingdom: Animal Phylum: Chordata Subphylum: Vertebrata Vertebrate characteristics: 1 – notochord (at least in the embryo)

What is comparative anatomy used for?

Comparative anatomy, the comparative study of the body structures of different species of animals in order to understand the adaptive changes they have undergone in the course of evolution from common ancestors.

What is the function of the brain in vertebrates?

Brain, the mass of nerve tissue in the anterior end of an organism. The brain integrates sensory information and directs motor responses; in higher vertebrates it is also the centre of learning. The human brain weighs approximately 1.4 kg (3 pounds) and is made up of billions of cells called neurons.

What is the vertebrate brain?

The vertebrate brain is the main part of the central nervous system. In vertebrates (and most other animals) the brain is at the front, in the head. It is protected by the skull and close to the main senses of vision, hearing, balance, taste, and smell. The capacity to learn is seen best in the cerebral cortex.

What are the 3 types of comparative anatomy?

Comparative Anatomy

  • Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.
  • Analogous structures are structures that are similar in unrelated organisms.

Who is the father of comparative anatomy?

The French zoologist Georges Cuvier (1769–1832), regarded as the father of modern comparative anatomy,…

What is comparative anatomy and why is it important?

Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.

What are examples of comparative anatomy?

A common example of comparative anatomy is the similar bone structures in forelimbs of cats, whales, bats, and humans. All of these appendages consist of the same basic parts; yet, they serve completely different functions.

What is an example of comparative embryology?

Embryology is a branch of comparative anatomy which studies the development of vertebrate animals before birth or hatching. Like adults, embryos show similarities which can support common ancestry. For example, all vertebrate embryos have gill slits and tails, as shown in Figure below.

What are the 9 parts of the brain?

These areas are: Occipital lobe, Temporal lobe, Parietal lobe, Frontal lobe. Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain. The image below indicates where the areas are. Occipital lobe: This is found in the back of the brain.

What are the 3 types of the brain?

The Architecture of the Brain The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1).

What is the scientific name for brain?

cerebrum: The cerebrum is the largest brain structure in humans, accounting for about two-thirds of the brain’s mass and positioned over and around most other brain structures. The cerebrum is divided into left and right hemispheres, as well as specific areas called lobes that are associated with specialized functions.

What is the most rostral brain division?

The most rostral of the three major divisions of the brain; includes the telencephalon and diencephalon. One of the two major portions of the forebrain, covered by the cerebral cortex. The region located within the brain, beneath the cortical surface.

How did the human brain evolve?

Human brain size evolved most rapidly during a time of dramatic climate change. Larger, more complex brains enabled early humans of this time period to interact with each other and with their surroundings in new and different ways.

How does the vertebrate brain develop?

The Structure of the Brain The developing brain goes through many stages. In the embryos of vertebrates, the predecessor to the brain and spinal cord is the neural tube. As the fetus develops, the grooves and folds in the neural tube deepen, giving rise to different layers of the brain.
