    Myotomes

    ByDr.Arati Gameti

    Myotomes are groups of muscles supplied by the motor fibers of a single spinal nerve root. A single neuron’s sensory fibers innervate a dermatome, which is a section of skin. Myocommata (plural: myocommata) is what separates myotomes. The part of a somite that turns into muscle during vertebrate development is called the myotome. Introduction Myotomes are spinal nerve roots that innervate a set of muscles (Greek: myo = muscle, tome = component, volume). When nerve radiculopathy is suspected, myotome testing is an important part of the neurological assessment. Since all skeletal muscles are innervated by nerves from several spinal cord levels, myotomes are even more difficult to evaluate than dermatomes. The somatic nervous system is composed of myotomes and is a component…

    Nerve Tissue Composition

    ByNitesh Dhameliya

    Nerve tissue is a fundamental component of the nervous system, responsible for transmitting signals throughout the body. Comprising of specialized cells called neurons, nerve tissue is characterized by its unique structure and function. What is a Nerve Tissue Composition? Within the neurological system, neurons are cells that send messages to other neurons, muscles, or gland…

    Central nervous system (CNS)

    ByNitesh Dhameliya

    What is a Central Nervous System? The central nervous system and the peripheral nervous system are two subtypes of the nervous system. The central nervous system is the brain and spinal cord, while the peripheral nervous system includes everything else. The central nervous system’s responsibilities involve receiving, processing, and responding to sensory information. Responses, sensations,…

    Lymphatic System

    ByAkshit Virani

    Overview Your lymphatic system is a network of organs, veins, and tissues that protect you from infection and maintain a healthy fluid balance throughout your body. Your bone marrow, thymus, and lymph nodes are all lymphatic system organs. Swollen lymph nodes are a symptom of both common infections, such as strep throat, and more serious…

  • Cellular Organelles

    ByAkshit Virani

    Introduction Cellular organelles are specialized structures within eukaryotic cells that perform various essential functions to maintain the cell’s integrity and carry out specific tasks. These microscopic compartments act like miniature factories, each with a unique role in the overall functioning of the cell. Organelles are enclosed by membranes, similar to the cell’s outer plasma membrane,…

    Immune System

    ByAkshit Virani

    Definition The Immune System is the body’s mechanism for preventing or inhibiting infection. It can protect the body against bacteria, viruses, parasites, and more because of its intricate network of cells, organs, proteins, and tissues. A working immune system can provide the difference between healthy tissue and foreign molecules. If an undesirable material, it will…

    Ventricles Of The Brain

    ByAkshit Virani

    Overview The Ventricles of the Brain are a connecting network of cavities inside the brain parenchyma that are filled with cerebrospinal fluid (CSF). The ventricular system is made up of two lateral ventricles, a third ventricle, the cerebral aqueduct, and a fourth ventricle (as shown in the figures below). The choroid plexuses in the ventricles…

    Antidiuretic Hormone (ADH)

    ByDr. Kavita

    What is an Antidiuretic Hormone (ADH)? Antidiuretic hormone (ADH), also known as vasopressin, is a peptide hormone produced by the hypothalamus and released from the posterior pituitary gland. Its primary function is to regulate the body’s retention of water, helping to maintain the body’s water balance and prevent dehydration. Introduction: The goal of ADH-level testing ADH…

    Cervical Lateral Flexion

    ByDr.Naisargi Patel

    What is Cervical Lateral Flexion? The cervical spine consists of seven vertebrae, and each vertebra is separated by intervertebral discs that allow flexibility and movement. Lateral flexion is one of the primary movements of the cervical spine, along with other movements such as flexion (bending forward), extension (bending back), and rotation (turning the head from…
