Chapter-1 Introduction to Human Anatomy and PhysiologyD.R. Chandravanshi
Anatomy (Greek anatomē, 'dissection') is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine.

The concept of planes and axes of movement is a complicated subject for both "nerds" and "novices" to fitness and exercise. This comprehensive infographic (brought to you by the folks at TodaysFitnessTrainer.com) attempts to take the mystery out of the topic and helps to simplify how the body moves in three-dimensional space.
Anatomy and physiology concerned with the structures and functions of the human body.
• Anatomy describes the structures of the body -- their scientific names, composition,
location, and associated structures. Anatomy (“a cutting open”) is a plan or map of the
body.
• Physiology studies the function of each structure, individually and in combination with
other structures.
• Anatomy and physiology always work together. As we examine each part of the body,
always consider both its structure and its function.

Human Anatomy and Physiology are the branches of biology that concerns with forms (structures) and functions of human body. ANATOMY- Study of structure of whole body and individual parts (organs) and their correlation with each other.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

11. Basic Life Processes
• Homeostasis
Equilibrium of the body’s internal
environment produced by the
interaction of organ systems and
regulatory processes (feedback
systems).
Homeostasis is a dynamic condition in
response to changing conditions.
The two body systems that largely
control the body’s homeostatic state:
1. Nervous system
2. Endocrine system
12. Control of Homeostasis
• Homeostasis is continually being disrupted by
– external stimuli
• intense heat, cold , and lack of oxygen
– internal stimuli
• psychological stresses
• exercise
• Disruptions are usually mild & temporary
• If homeostasis is not maintained, death may result
13. CONTROL OF HOMEOSTASIS
• Homeostatic imbalances occur because of disruptions
from the external or internal environments.
– Homeostasis is regulated by the nervous system and
endocrine system, acting together or independently.
– The nervous system detects changes and sends nerve
impulses to counteract the disruption.
– The endocrine system regulates homeostasis by
secreting hormones.
• Whereas nerve impulses cause rapid changes, hormones
usually work more slowly.
• Examples: CO2, O2, temperature, pH, blood pressure, …
14. Example of Homeostasis
Fluid balance in the Body
• Compartments
for Body Fluids
2. Intracellular
3. Extracellular
a. Interstitial
b. Plasma
15. Components of Feedback Loop
• Receptor
– monitors a controlled condition
• Control center
– determines next action
• Effector
– receives directions from the control
center
– produces a response that changes the
controlled condition
18. Homeostatic Imbalances
• Disruption of homeostasis can lead to disease and death.
• Disorder is a general term for any change or abnormality
of function.
• Disease is a more specific term for an illness characterized
by a recognizable set of signs and symptoms.
– A local disease is one that affects one part or a limited
region of the body.
– A systemic disease affects either the entire body or
several parts.
19. Homeostatic Imbalances
• Disease is a more specific term for an illness characterized
by a recognizable set of signs and symptoms.
– Signs are objective changes that a clinician can observe
and measure; e.g., fever or rash.
– Symptoms are subjective changes in body functions
that are not apparent to an observer; e.g., headache or
nausea.
• Diagnosis is the art of distinguishing one disease from
another or determining the nature of a disease; a diagnosis
is generally arrived at after the taking of a medical history
and the administration of a physical examination.
20. Anatomical Position
• The anatomical position is a standardized
method of observing or imaging the body
that allows precise and consistent
anatomical references.
• When in the anatomical position, the subject
stands (Figure 1.5).
– standing upright
– facing the observer, head level
– eyes facing forward
– feet flat on the floor
– arms at the sides
– palms turned forward (ventral)
27. Directional Terms Used to Describe the
Position of one Structure to Another

(Cephalic/Caudal)
Anterior/Posterior
(Ventral/Dorsal)
Medial/Lateral
Intermediate: Between
