  How many parts body divide?

  According to anatomy studies [50], human body parts can be divided into nine different parts by position: the head, neck, chest, abdomen, pelvis, back, hip, extremity, and trunk.

  Which group of animal is invertebrates?

  The 9 Main Phyla of Invertebrates

  Groups of Invertebrate Animals	Examples
  Phylum Cnidarians	Jellyfish, corals, anemones, hydra
  Phylum Platyhelminthes	Flatworms, flukes, tapeworms
  Phylum Echinodermata	Sea stars, brittle stars, sea urchins, sea cucumbers
  Phylum Mollusca	Snails, clams, squids, octopi, other mollusks

  How is divided the human body?

  The human body is a single structure but it is made up of billions of smaller structures of four major kinds: cells, tissues, organs and systems. The body is composed of ten major systems: Skeletal, Muscular, Nervous, Cardiovascular, Lymphatic, Respiratory, Digestive, Endocrine, Urinary, and Reproductive.

  Is a worm a reptile or an insect?

  Most animals called “worms” are invertebrates, but the term is also used for the amphibian caecilians and the slowworm Anguis, a legless burrowing lizard.

  What is the classification of worms?

  Worms are members of several invertebrate phyla, including Platyhelminthes (flatworms), Annelida (segmented worms), Nemertea (ribbon worms), Nematoda (roundworms, pinworms, etc.), Sipuncula (peanutworms), Echiura (spoonworms), Acanthocephala (spiny-headed worms), Pogonophora (beardworms), and Chaetognatha (arrowworms).

  What are the two parts the body is divided into?

  A coronal or frontal plane divides the body into dorsal and ventral (back and front, or posterior and anterior) portions. A transverse plane, also known as an axial plane or cross-section, divides the body into cranial and caudal (head and tail) portions.

  In which two categories can a human body be divided to understand?

  the head, the trunk and the limbs (extremities).

  What are the 5 invertebrate groups?

  The Invertebrates unit explores six groups of invertebrates— poriferans (sponges), cnidarians (such as sea jellies and corals), echinoderms (such as sea urchins and sea stars), mollusks (such as octopuses, snails, and clams), annelids (worms), and arthropods (such as insects, spiders, and lobsters).

  What are the 8 classifications of invertebrates?

  Classification of invertebrates

  • Sponges (Porifera)
  • Comb jellies (Ctenophora)
  • Hydras, jellyfishes, sea anemones, and corals (Cnidaria)
  • Starfishes, sea urchins, sea cucumbers (Echinodermata)
  • Flatworms (Platyhelminthes)
  • Earthworms and leeches (Annelida)
  • Insects, arachnids, crustaceans, and myriapods (Arthropoda)

    What is the main part of human body?

    Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver and lungs. The human brain is the body’s control center, receiving and sending signals to other organs through the nervous system and through secreted hormones.

    What are the different types of body parts?

    This list of human body parts includes common anatomical divisions and the body parts that compose those divisions. The study of the macroscopic morphology and function of the human body is called gross anatomy. In general, the human body can be divided into 3 main anatomical areas: head, torso, and limbs.

    How are the limbs of the human body divided?

    The main limbs of the human body are: In addition to dividing the human body by anatomical region, one can also categorize the parts of the human body by organ system. In a nutshell, an organ system is a collective group of organs that work together to perform some specific function.

    What are the two major regions of the body?

    Just like on a map, a region refers to a certain area. The body is divided into two major portions: axial and appendicular. The axial body runs right down the center (axis) and consists of everything except the limbs, meaning the head, neck, thorax (chest and back), abdomen, and pelvis.

    Can a body be divided into two identical halves?

    The body can be divided into two identical halves in any plane that runs through the organism’s cen­tre. In asymmetrical symmetry and spherical symmetry the polarity does not exist and spherical symmetry is seen in radiolarian protozoa (Fig. 9.2). Type # 3. Radial Symmetry:

    What are the five parts of the declaration of Independence?

    The Declaration of Independence is divided up into five parts: 1 Introduction 2 Preamble 3 Body – Section 1 4 Body – Section 2 5 Conclusion
