Cross section
A cut in the transverse (horizontal) plane
Abdominal
Abdomen

Loin
Midsagittal section
Passes through the midline. It separates the body into equal right and left sides.
Antebracial
Forearm
Posterior
The back surface
Respiratory System
Delivers air to sites where gas exchange occurs between the air and circulating blood, produces sound
Cervical
Neck
Urinary System
Eliminates excess water, salts, and wastes, controls pH
Parasagittal section
Misses the midline. It separates the body into unequal right and left sides.
Transverse plane
(Horizontal plane) Separates superior and inferior portions of the body
Cardiovascular System
Transports cells and dissolved materials in the bloodstream, including nutrients, wastes, and gases
Calcaneal
Heel of foot
Anterior
The front surface
Mental
Chin
Hallux
Great toe
Dorsal
Back
Pubic
Pubis
Otic
Ear
Buccal
Cheek
Pelvic
Pelvis
Frontal plane
Separates anterior and posterior portions of the body.
Lymphatic System
Defends against infection and disease, returns tissue fluid to the bloodstream
Medial
Toward the midline
Digits (phalanges)
Fingers
Nervous System
Directs immediate responses to stimuli, usually by coordinating the activities of other organ systems
Tarsal
Ankle
Popliteal
Back of knee
Proximal
Toward the point of attachment of a limb to the trunk
Deep
Toward the interior of the body; farther from the surface
Trunk
Thoracic, mammary, abdominal, umbilical, pelvic
Cephalic
Head: cranial and facial
Ocular
Eye
Coronal plane
Separates anterior and posterior portions of the body, coronal usually refers to sections passing through the skull.
Superficial
At, near, or relatively close to the body surface
Oral
Mouth
Carpal
Wrist
Thoracic
Thorax/chest
Inguinal
Groin
Inferior
Below; at a lower level; toward the feet
Nasal
Nose
Dorsal
The back
Axillary
Armpit
Brachial
Arm
Superior
Above; at a higher level (in the human body, toward the head)
Digits (phalanges)
Toes
Plantar
Sole of foot
Cranial or Cephalic
Toward the head
Lateral
Away from the midline
Palmar
Palm
Horizontal plane
(Transverse) separates superior and inferior portions of the body.
Viscera
Internal organs that are partially or completely enclosed.
Pericardial cavity
The fluid filled space between the outer and inner layers of the serous pericardium.
Pericardium
Surrounds the heart
Serous membrane
Covers the viscera and lines the true body cavities of the trunk. Secretes a watery fluid that reduces friction and keeps the surfaces moist.
Diaphragm
A muscular sheet that separates the thoracic cavity from the abdominopelvic cavity.
Pleural cavity
Holds each lung
Pleura
Lines the pleural cavity. Is a shiny, slippery serous membrane
Mediastinum
A mass of connective tissue that separates the two pleural cavities and stabilizes the positions of embedded organs and blood vessels.
Peritoneal cavity
A chamber lined by a serous membrane known as the peritoneum.
Peritoneum
The serous membrane that lines the peritoneal cavity
Retroperitoneal
Organs that lie between the peritoneal lining and the muscular wall of the abdominal cavity. (Kidneys and pancreas)
Infraperitoneal
Organs such as the urinary bladder and the distal portions of the ureters and large intestine, which extend inferior to the peritoneal cavity, are said to be this.
Coxal
Hip
Fibular
Side of the leg
Peroneal
Side of the leg
Manus
Hand
Dorsum
Back
Occipital
Posterior aspect of the head or base of the skull
Perineal
Region between the anus and external genitalia
Sacral
Region between the hips (overlying the sacrum)
Scapular
