What is the skeletal system

Anatomy: Is the study of the structure of the body. Skeletal System Osteology is the branch of anatomy that describes the structure & functions of the human skeletal system. the adult human skeletal system is composed of 206 bones, numerous ligaments & cartilage, the skeleton is the bony framework that gives shape of the body by making joints with each other provides attachment of the muscles & tendons & tendons & protects the vital organs from external injury. Skeleton: Bone & cartilaginous framework of the body. Bone: Are the strong & hardly structure. Most of the bones are hollow & contains bone marrow, which produces red blood cells & white blood cells also a great reservoir of calcium ions. Ligament...

What is the Muscular System

Myology is the branch of anatomy, which describes the muscular system, its components, structure & functions. it forms the flesh of the flesh of the body, which fives the body strength & helps for locomootion (movement). The muscular system functions in close relation with the skeletal system & sometime regarded as one system called musculoskeletal system. Muscles are composed of muscle fibers & grossly of three types: 1, Smoth muscles (Visceral muscle) are involuntary, present in the wall of GIT, blood vessel & other internal organs that are innervated by autonomic nervous system. 2, Cardiac muscle or involuntary, present in the heart only. it has a special property that it can produce...

Organs of Digestive System

Digestion: it is a physiological process by which complex complex food particles are broken down into simple form for absorption & subsequent utilization. Organs of Digestive System: Gastrointestinal Tract 1, Oral Cavity (Mouth) 2, Oropharynx 3, Esophagus 4, Stomach 5, Small Intestine a)      Duodenum b)      Jejunum c)      Ileum 6, Large Intestine – a. Caecum                             b. Ascending Colon c. Transverse Colon                d. Descending...

The Urinary System

Excretion: It is a process by which the unwanted & end product of our body are removed from the body. Excretory System includes: Urinary system, The Bowels, The skin, the Lungs, Saliva, Breast milk. Urinary system: is the major excretory system. the Organs of Urinary System are – 1, Two Kidnneys- the major excretory organ. 2, Two Ureter- the tube which collect urine from kidney to Urinary Bladder. 3, One Urinary Bladder- the bladder which acts as a reservoir of urine. 4, Urethra- the small tube which expel urine from body to outside. Urination Process: Urine is collected from Kidney to urinary bladder through ureter. Then expelled out by urethra. Some common diseases of Urinary System: 1, Urethritis – Inflammation of urethra. 2,...

Respiratory System

Respiration: It is the process by which oxygen ( O2 ) is carried from the atmosphere to the tissue for oxidation & carbon dioxide ( CO2 ) formed in the tissue is expired out. The system involved in this process is called Respiratory system. Organs of Respiratory system: It is divided into two parts. Upper Respiratory Tract 1, Nasal cavity 2, Pharynx 3, Larynx 4, Trachea Lower Respiratory Tract 1, Lungs 2, Bronchi 3, Bronchiole 4, Alveolar duct 5, Alveoli Special Organs 1, Tonsils 2, Sinus 3, Ear Sinus – an air cavity within the bones of Skull (or face). Tonsil – a mass of lymphoid tissue on either side of the back of mouth. It protects infection. Lymphoid tissue – responsible for the production of lymphocytes ( a variety...

Cardiovascular/ Cieculatory System

Kardia ( latin word ) means Heart & Vasculum ( latin word ) means Vessele. So Cardiovascular system consists of Heart & Blood Vessele. So Cardiovascular system consists of Heart & Blood vessels. Cardiovascular system also known as Blood Circulatory System (as it circulates blood in the body). Definition: The circulatory system is an organ system that moves nutrients, gases & wastes to & from cells, helps fight diseases & helps stabilize body temperature & pG to maintain homeostasis (equilibrium). Organs of Cardiovascular system: 1, Heart 2, Blood vessels 3, Blood Heart: It is a central pumping station which circulates blood to/from body by contraction & dilation. Heart receives blood by coronary blood vessel. Blood...

Classification of Nervous System

Nervous System is the most important system which control & integrates the different body functions & maintains the constancy of internal environment despite of extreme change in external environment. Classification of Nervous System: 1, Central Nervous System – It consists of Brain (cranial part) & Spinal Cord. 2, Peripheral Nervous System – It consists of Cranial nerves (12pairs) & Spinal nerves (31 pairs). Organs of Nervous System: 1, Brain -                      The enlarged & highly developed mass of nervous tissue contained within the cranium that forms the upper end of the CNS & is continuous...

The Endocrine System

Endo means internal & crinos means secretion. So Endocrine means internal secretion. Endocrinology is a branch of medical science which deals with the study of different endocrine glands of the body. Endocrine gland: Means ductless gland which directly poured their secretion into the blood. Endocrine system: The system which deals with endocrine glands & their secretions. Organs of Endocrine System: The Endocrine System consists of the following glands. 1, Pineal gland 2, Hypothalamus 3, Pituitary gland – Anterior part & Posterior part. 4, Thyroid gland 5, Para – thyroid gland 6, Adrenal gland – Adrenal cortex & Adrenal medulla 7, Pancreas 8, Testis 9, Ovary 1, Pineal gland: A pea-sized mass of tissue attached by a stalk to the posterior wall of the...

What is the Limbic System

Limbic System: It is a complex system of nerve pathways & networks in the brain, involving several different nuclei, that is involved in the expression of instinct & mood in activities of the endocrine & motor system of the body. Function: Emotion, Intelligence, Mood Feeling, Memory, etc Organs: Thalamus, Basal ganglia, Hippocampus & Amygdale. Thalamus: One of two egg-shaped masses of gray matter that lies deep in the cerebral hemispheres in each side of the forebrain. The thalamus is relay stations for all the sensory messages that enter the brain, before they are transmitted to the cortex. Basal ganglia: Several large masses of gray matter embedded deep within the white matter of the cerebrum. The basal ganglia...

Lymphatic System

Organs: Lymphatic capillaries, Lymphatic vessels, Lymphatic nodes & Lymphatic ducts. Function:     1, Collection of fluid & Protein from tissue spaces & back to                          blood Stream.                      2, Filtration of blood & formation of fresh lymphocytes.                      3, Excretion, Defense, Circulation, etc. Lymphatic System: A network of vessels that conveys electrolytes, water, proteins,...
