Down syndrome

-
 Down syndrome is a genetic disorder caused by an extra copy of chromosome 21. This results in developmental and intellectual delays. People with Down syndrome often have distinct facial features, such as a flat face and upward-slanting eyes, and may experience health issues like heart defects and thyroid problems. **Key Points:** - **Physical Features:** Flat facial profile, short neck, small ears, and almond-shaped eyes. - **Health Concerns:** Increased risk of heart defects, respiratory issues, hearing problems, and thyroid conditions. - **Development:** Delays in milestones such as walking and talking; intellectual disability ranges from mild to moderate. **Causes:** - An error in cell division results in an extra chromosome 21. Types include Trisomy 21, Mosaic Down syndrome, and Translocation Down syndrome. **Diagnosis:** - During pregnancy through screening and diagnostic tests, and after birth through physical characteristics and chromosomal analysis. **Support:** - Early in...

Let's start with the first question about the cerebellum. ### 1. Connections & Functions of the Cerebellum #### Connections The cerebellum, located at the back of the brain beneath the occipital lobes, has several important connections that facilitate its role in motor control: - **Afferent Connections**: The cerebellum receives input from the spinal cord, brainstem, and cerebral cortex.   - **Spinal Cord**: The spinocerebellar tracts bring proprioceptive information from muscles and joints.   - **Brainstem**: Vestibulocerebellar tracts bring information from the vestibular nuclei, related to balance.   - **Cerebral Cortex**: The cerebrocerebellar pathway involves the cerebral cortex sending information via the pontine nuclei to the cerebellum, which helps in planning and initiating movements. - **Efferent Connections**: The cerebellum sends output to the cerebral cortex and brainstem.   - **Cerebrocerebellar Output**: The dentate nucleus projects to the thalamus...

 Sure, let's go through each topic one by one: ### Endocrine System #### 1. Enumerate the hormones of the pituitary gland. Add a note on Growth Hormone. **Hormones of the Pituitary Gland:** - **Anterior Pituitary (Adenohypophysis):**   1. Growth Hormone (GH)   2. Thyroid-Stimulating Hormone (TSH)   3. Adrenocorticotropic Hormone (ACTH)   4. Follicle-Stimulating Hormone (FSH)   5. Luteinizing Hormone (LH)   6. Prolactin (PRL) - **Posterior Pituitary (Neurohypophysis):**   1. Oxytocin   2. Antidiuretic Hormone (ADH) or Vasopressin **Note on Growth Hormone (GH):** Growth Hormone, also known as somatotropin, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important for human development. GH also has significant effects on metabolism. #### 2. Thyroid hormone – secretion, regulation & functions, and applied aspects **Secretion:** Thyroid hormones are primarily T3 (tri...

 ## General Physiology ### Long Answer Questions 1. **Transport Mechanisms Across the Cell Membrane**    The cell membrane, or plasma membrane, is a dynamic structure that plays a crucial role in controlling the movement of substances in and out of cells. The various mechanisms of transport include:    - **Passive Transport**:      - **Simple Diffusion**: Molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer. This process does not require energy. Examples include the diffusion of oxygen and carbon dioxide.      - **Facilitated Diffusion**: Utilizes specific transport proteins to move substances down their concentration gradient. These proteins include channel proteins and carrier proteins. An example is the glucose transport into cells.      - **Osmosis**: A specific type of passive transport involving the movement of water molecules through a selectiv...

  **SAQ** 1. **Genetic Code and Wobble Hypothesis for Codon-Anticodon Interactions**    **Genetic Code**:    - The genetic code is a set of rules by which information encoded in DNA or mRNA sequences is translated into proteins by living cells. It is universal, nearly identical among all organisms, and consists of 64 codons.    - Codons are sequences of three nucleotides, each codon specifies a particular amino acid.    - There are 61 codons for amino acids and 3 stop codons (UAA, UAG, UGA) which signal the termination of protein synthesis.    **Wobble Hypothesis**:    - Proposed by Francis Crick, the wobble hypothesis explains the flexibility in the base-pairing rules between the 5' base of the tRNA anticodon and the 3' base of the mRNA codon.    - The third base of the codon (3’ end) and the first base of the anticodon (5’ end) can form non-standard pairings, allowing a single tRNA to recognize multiple codons....

  ## SAQ ### 1. Define a balanced diet. Discuss protein-energy malnutrition with the nutritional importance of proteins. **Balanced Diet:** A balanced diet provides all essential nutrients in the right proportions to maintain health, growth, and proper body function. It typically includes: - Carbohydrates: for energy. - Proteins: for growth, repair, and enzyme production. - Fats: for energy, cell function, and absorption of vitamins. - Vitamins and minerals: for various biochemical functions. - Water: for hydration and physiological processes. - Fiber: for digestive health. **Protein-Energy Malnutrition (PEM):** PEM occurs when there is a deficiency of proteins and calories in the diet. It is prevalent in developing countries, particularly among children. PEM manifests in two major forms: - **Kwashiorkor:** Characterized by edema, an enlarged liver, skin lesions, and hair changes. It results from protein deficiency with adequate caloric intake. - **Marasmus:** Characterized by seve...

SAQ of concept of health and disease  1. **Human Development Index (HDI):** A composite index that measures a country's average achievements in three basic aspects of human development: longevity, knowledge, and a decent standard of living. 2. **Theories of Causation of Diseases:** These theories explain how diseases occur. Examples include the germ theory, which suggests that diseases are caused by microorganisms, and the multifactorial theory, which states that diseases result from the interaction of multiple factors. 3. **Indicators of Health:** Measures used to assess the health status of individuals or populations, such as mortality rates, life expectancy, morbidity rates, and quality of life indicators. 4. **Dimensions of Health:** Various aspects of health, including physical, mental, social, and emotional well-being. 5. **Iceberg Phenomenon of Disease:** Describes the concept that only a small proportion of cases of a particular disease are visible or clinically evident, wh...
