1. Morphology of Viruses: Virology: The scientific study of viruses is known as virology. Structure: Viruses are acellular entities consisting of genetic material (either DNA or RNA) surrounded by a protein coat called a capsid. Capsid Shapes: Capsids can have various shapes, including helical, icosahedral, or complex. Envelope: Some viruses have an additional lipid envelope … Read more
Study of Fungi: 1. Morphology of Fungi: Mycology: The scientific study of fungi is known as mycology. Body Structure: Fungi exhibit diverse morphologies. The fungus has a main body called a thallus, which can exist in either a unicellular form (yeasts) or a multicellular form (molds and mushrooms). Hyphae: The multicellular fungi consist of thread-like … Read more

A stroke, also known as a cerebrovascular accident (CVA), occurs when there is a sudden interruption of blood flow to the brain, leading to the damage or death of brain cells. Strokes can be ischemic, caused by a blockage in the blood vessels supplying the brain, or hemorrhagic, caused by bleeding within the brain. Etiopathogenesis: … Read more
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that primarily affects cognitive functions, particularly memory, thinking, and behavior. It is the most common cause of dementia, a condition characterized by a decline in cognitive abilities severe enough to interfere with daily life. Etiopathogenesis: The exact cause of Alzheimer’s disease is not fully understood, but it … Read more
Parkinson’s disease (PD) is a progressive neurodegenerative disorder that primarily affects movement. It is characterized by the loss of dopamine-producing neurons in the substantia nigra region of the brain, leading to motor and non-motor symptoms. Etiopathogenesis: 1. Dopamine Depletion: Progressive loss of dopamine-producing neurons in the substantia nigra. 2. Lewy Bodies: Accumulation of abnormal protein … Read more
Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures. Seizures are episodes of abnormal electrical activity in the brain that lead to various symptoms, ranging from brief periods of unconsciousness to unusual movements or sensations. Etiopathogenesis: 1. Idiopathic (Primary) Epilepsy: No identifiable cause; likely genetic factors play a role. 2. Symptomatic (Secondary) Epilepsy: Structural … Read more
Hypothyroidism: Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), leading to a slowdown of various bodily functions. Etiopathogenesis: 1. Autoimmune Thyroiditis (Hashimoto’s Thyroiditis): An autoimmune disorder where the immune system attacks the thyroid gland, leading to inflammation and gradual destruction of thyroid tissue. … Read more
Definition: COPD is a progressive respiratory disease characterized by chronic airflow limitation due to inflammation of the airways and destruction of lung tissue. The term COPD encompasses two main conditions: chronic bronchitis and emphysema. It is often associated with exposure to harmful gases or particles, primarily cigarette smoke, but also environmental pollutants. Etiopathogenesis: 1. Smoking: … Read more
