8 Body Cavities The body has 2 main cavities: – Dorsal cavity (back). – Ventral cavity (front). Pelvic cavity Abdomin al cavity Diaphrag m Thoraci c cavity Crani al cavity Dorsal cavity Ventral cavity Spinal cavity

9 Dorsal Cavity Located on the posterior (dorsal) side of the body It consists of 2 cavities 1.Cranial Cavity - The bones of the skull create the cranial cavity to protect the brain 2.Spinal (vertebral) Cavity -Formed by the vertebrae of the spine that surrounds the spinal cord.

10 Ventral Cavity Ventral Cavity – located on the anterior/ventral side of the body. It is made up of three cavities. Two are divided by the diaphragm.

11 Thoracic Cavity This is the portion of the Ventral Cavity superior to the diaphragm. It contains the heart, lungs and major vessels

12 Abdominal Cavity Located inferior to the diaphragm. It includes the following organs: Stomach Spleen Liver Gallbladder pancreas Small intestine Most of the large intestine

13 Pelvic Cavity The pelvic cavity is surrounded by the pelvic bones. The pelvic cavity contains: Urinary bladder male and female reproductive organs Parts of the digestive system

14 Planes of the body Body planes are imaginary lines that divide the body into sections – Midsagittal plane – divides the body into equal right and left sides. – sagittal plane – divides the body into 2 parts, right and left. – Frontal or coronal plane – divides the body into anterior and posterior sections. – Transverse plane – divides the body horizontally into a top, or superior, part and a bottom, or inferior, part.

15 Planes of the body Inferior Midsagittal Transverse Frontal Superior Anterior Lateral Posterior Distal Proximal Medial

16 Midsagittal Plane Divides body into equal right & left halves.

17 Frontal (Coronal) Plane Divides body into front & back portions

18 Transverse Plane Divides body into upper & lower portions.

19 Abdominal Quadrants The abdominal/pelvic cavity is so large that it is divided into regions One method of division is quadrants. Quadrants divide the abdominal/pelvic cavity into four sections using the belly button as the point of reference for both the horizontal and vertical lines

20 Abdominal Regions A more precise method of division is abdominal regions. This method divides the area into a tic tac toe board Epigastric – above the stomach Umbilical - near the belly button Hypogastric –below the stomach Hypochondriac – below the ribs Lumbar/Lateral – in between the hypocondriac and iliac Iliac/inguinal – near the groin
