For this assignment I will be describing and discussing the major anatomical regions, directions and cavities of the human body. I will first start with listing the anterior, which means in front, anatomical regions.
These are the list of the anterior anatomical regions starting from superior, toward the head, to inferior, towards the feet: The frontal (forehead), orbital (eye), nasal (nose), buccal (cheek), oral (mouth), mental (chin), cervical (neck), acromial (point of shoulder), sterna (breastbone), thoracic (chest), axillary (armpit), mammary (breast), abdominal (abdomen), brachial (arm), antecubital (front of elbow), antebrachial (forearm), umbilical (navel), pelvic (pelvis), carpal (wrist), pollex (thumb), palmar (palm), digital (fingers), coxal (hip), inguinal (groin), pubic (genital region), femoral (thigh), patellar (anterior knee), crural (leg), fibular, or peroneal (side of leg), pedal (foot) which has the tarsal (ankle) and digital (toes), and hallux (great toe). This concludes the anterior direction of the anatomical regions.
These are the list of the posterior, which means in back, from superior to inferior: otic (ear), occipital (back of head or base of skull), acromial (base of shoulder), vertebral (spinal column), scapular (shoulder blade), brachial (arm), dorsum or dorsal (back), olecranal (back of elbow), lumbar (loin), sacral (between hips), gluteal (buttock), perineal (region between the anus and external genitalia), femoral (thigh), popliteal (back of knee), sural (knee), calcaneal (heel), and plantar (sole). I have already discussed the superior, inferior, anterior, and posterior directions of the body. Here is a list of the other anatomical directions of the body: medial and lateral, proximal and distal, and superficial and deep.
Medial is towards the middle of your body, like going inwards, and lateral is towards the outside of your body, head outwards and away from your body. Proximal is closer to the point of where it attaches and distal is furthest away from where it attaches. Superficial is more towards the surface, external, or outward while deeps means that its internal, inwards, or below the surface. To conclude, I will be discussing the various body cavities and the organs within them. The organs in the human body lie mostly within two cavities which are the dorsal and ventral cavities. The dorsal cavity starts at your head and ends at the base of your spine. A part the dorsal cavity is the cranial cavity, which houses the brain, and the spinal cavity, which houses the spinal cord.
The ventral cavity has many organs within itself and it’s broken down into two main subdivisions which are the thoracic and abdominopelvic cavity. These two cavities are separated by the diaphragm muscle. You could also say that the abdominal cavity and pelvic cavity are a part of the ventral cavity but nothing separates the two, so it is acceptable to use the abdominopelvic cavity term. The organs inside the thoracic cavity are the heart, lungs, trachea, esophagus, and the thyroid gland. The organs inside the abdominopelvic cavity are the liver, gallbladder, stomach, spleen, pancreas, intestines, colon, rectum, urinary bladder, and reproductive organs.
