Supine position
The body is lying face up
Prone position
The body is lying face down
Anatomical terms
Cephalic, Cervical, Trunk, Upper Limbs, Lower Limbs, Acromial, and Pectoral
Cephalic
Head (skull and face)
Cervical
Neck (supports head and attaches to trunk)
Trunk
Chest, abdomen, and pelvis
Upper limbs
Attaches to trunk (shoulder, armpit, arm, and hands)
Lower limbs
Attaches to trunk (buttocks, hip, thigh, leg, ankle, and foot)
Acromial
the top of the shoulder
Pectoral
Anterior chest
Anterior
front
Posterior
Back

Inferior
Below
Midline
an imaginary line that divides the body into equal right and left sides
Medial
Closer to the midline
Lateral
Farther from the midline
Proximal
Nearer to the attachment of a limb to the trunk
Distal
Farther from the attachment of a limb to the trunk
Superficial
Closer to the surface of the body
Deep
Deeper inside the body
Intermediate
Between two structures
Ipsilateral
On the same side of the body
Contralateral
On the opposite sides the body
Planes
Imaginary flat surfaces that pass through the body and body parts
Section
results from a cut through the plane
Dissection
Means to cut or to make a section
Sagittal plane
A vertical plane that divides the body into right and left sides
Midsagittal plane
Divides the body or organ into equal right and left sides
Parasagittal plane
Divides the body or organ into unequal right and left sides
Front or coronal plane
Divides the body or an organ into anterior and posterior
Transverse or horizontal plane
Divides the body or an organ into superior and inferior portions
Cranial cavity
Surrounded by the cranial bones
Vertebral canal
Surrounded by the cranial bones
Thoracic cavity
is also called the chest cavity, surrounded by ribs, muscles of the chest, sternum, and vertebral column in the back
Diaphragm
a dome-shaped muscle that separates the thoracic cavity from the abdominopelvic cavity
What are the 3 cavities in the thoracic cavity?
Pleural, mediastinum, and pericardial
Pleural cavities
The lungs fill up most of these spaces
Mediastinum
Medial to the lungs, contains the pericardial cavity
Pericardial cavity
Located within the mediastinum, the heart fills up most of the pericardial cavity space
Abdominopelvic cavity
the cavity inferior to the diaphragm
Abdominal cavity
Contains the stomach, spleen, liver, gallbladder, small and large intestines
Pelvic cavity
Contains the bladder, internal organs of the reproductive system, contains part of the large intestine
Viscera or visceral organs
internal organs in the thoracic and abdominopelvic cavities
Serous membrane
is a thin slippery membrane that covers the viscera and lines the cavity’s walls
Parietal later of the serosa
Lines the wall of the cavities in the trunk
Visceral layer of the serosa
Covers the viscera within these cavities
Peritoneal cavity
the cavity surrounded by the parietal peritoneum
Synovial (joint) cavities
Cavity in moveable joints
