Anatomy Intro

 Heyy guys... Welcome back to my another blog. Today you will get to know about some introduction of anatomy.

Before starting this blog go & follow this blog page "PhysioZon" also FB page"PhysioZon" and Instagram "physiozon.sm" to get notifications of my posts.

Let's begin....

# What is human anatomy?

:  Human anatomy is a science that related with the structural features of the human body.

  The term 'Anatomy' is derived from a Greek word 'anatome' meaning cutting up. The term 'dissection' is a latin equivalent of the Greek anatome. But the anatomy and dissection are not synonymous.

  There are various branches of it, some of them are...

Gross anatomy, micro-anatomy, clinical anatomy, embryology, radiological anatomy, surface anatomy etc.

# What are the postures in anatomy?

:  I) Anatomical position : In this position a person is standing erect, eyes looking towards horizon, arms is by the side of the trunk, palm facing forwards.

  II) Fundamental position : This is like anatomical position except the palm is on the side of the trunk which is the usual position in our posture.

Patients are examined in this position.

  III) Supine position : Subject is lying on the back with face up.

  IV) Prone position : Subject is lying with the face down and belly on the table.

  V) Lateral position : The side of the subject is adjacent to the table.

# What are the anatomical planes ?

:  I) Sagittal plane : This divides the body into two equal halves, running length wise from front to back.

  II) Coronal plane : This divides the body into anterior and posterior portion, running length wise from side to side. It is also known as frontal plane.

 III) Transverse plane : This is a cross wise plane divides the body into upper and lower parts. It is also known as horizontal plane.

# Some anatomical terms with examples....

• Superior = The head is superior to the neck.

• Inferior = Navel is inferior to the chest.

• Anterior or ventral = Navel is anterior or ventral.

• Posterior or dorsal = Spine is posterior or dorsal.

• Medial = Towards the midline of the body.

• Lateral = Away from midline of the body.

• Proximal = Closest to the trunk (shoulder joint).

• Distal = Away from the trunk (wrist joint).

• Superficial = Closest to the body surface (skin).

• Deep = Away from the body surface (muscles).

# What do we learn in anatomy ?

:  In anatomy we learn about human body.

  We learn about skeleton, skeletal system of human body, bones of human body, joints of human body, muscular system of human body, muscles of human body, nervous system of human body, arterial system of human body, veins of human body, lymphatic system of human body, visceral organs of human body etc.

#What is skeleton ? 

:  Skeleton is formed by bones and cartilages. It is the main supporting framework of the body. It is primarily designed for a more effective production of movements by the attached muscles.

  It is composed of 270 bones at birth. This total decreases to around 206 bones by adulthood after some bones get fused together.

# What is skeletal system ?

:  It is a network of many different parts that work together to help to move.

  The main part of skeletal system is the skeleton and the joints.

# What is bone?

:  Bones are specialized connective tissue known as sclerous tissue. Bone is one-third connective tissue. It is impregnated with calcium salts which constitute two-thirds part.

  Bones give shape and support to the body. It store 97% of the body calcium and phosphorus.

  There are various types of bones present in the human body. You will know about them in further blogs..stay tuned...

# What is joint ? 

:  Joint is a junction between two or more bones, cartilages with bones or cartilage with cartilage.

  There are more joints in a child than in an adult because as growth proceeds some of the bones fuse together.

•Example= the ilium, ischium and pubis to form the pelvic bone.

# What is muscle ? 

: "Muscle" name came from Latin word "mus" which means mouse like appearance.

  Muscle is a tissue which has the special contractile property due to presence of abundant actin and myosin protein filament.

  Muscle cells are known as myocytes.

# What is muscular system ? 

:  The muscular system is an organ system consisting of three types of muscles = skeletal muscle, smooth muscle and cardiac muscle.

  It permits movements of the body, maintains posture and circulates blood throughout the body.

# What is nerve ?

:  A nerve is a cable like bundle of fibers called axons, surrounded by a sheath, sends messages between the body and the brain by chemical and electrical changes in the cells (neurons).

# What is nervous system ?

:  Nervous system is the main controlling and coordinating system of the body.

  It controls and regulates all activities of the body. The structural and functional unit of nervous system is neuron.

  Nervous system divided into central nervous system (CNS) and peripheral nervous system (PNS). Functionally,it is again divided into somatic nervous system and autonomic nervous system.

# What is artery ?

:  Arteries are the blood vessels that deliver oxygenated blood from the heart to the tissues of the body.

# What is vein ?

:  Veins are a type of blood vessels that carries deoxygenated blood from the tissues of the body to the heart.

# What is lymph ?

:  Lymph is a clear to white like fluid, made of white blood cells.

# What is viscera?

:  Viscera are the internal organs of the human body.

•Example = lungs, liver, pancreas etc.

Hope these information will help you a lot...
