The Human Body: Anatomical Terms (#1)

Friday, October 31st, 2008

Aditus: an entrance or opening

Ala: a wing-like process

Alveolus: a deep narrow pit, such as a tooth-socket

Ampulla: used to describe the dilated part of a duct

Ansa: a loop, usually referring to a nerve

Antrum: a cavity

Aponeurosis: a glistening sheet of fibrous connective tissue from which muscle fibers arise or into which they runv

Artery: a blood vessel which conducts blood from the hear

Bone: a special form of connective tissue in which calcium salts are deposited and which provides a framework, or skeleton, for the other tissues of the body

Bursa: a membranous sac containing a small amount of viscous fluid. A bursa is usually found in tissues where friction develops, such as where a tendon crosses a bony prominence. A bursa may form synovial sheaths to surround tendons as they cross other tendons or bone

Canalva and relatively narrow channel, or tunnel, often through a bone. A canaliculus is a smaller canal

Capsule: a fibrous or membranous envelope surrounding an organ. An articular capsule surrounds each synovial joint, being attached to the bones just beyond the limits of the joint cavity

Cartilage: a firm white tissue, from which most parts of the bony skeleton are formed and which persists to protect the surfaces of bones and joints

Caruncle: a small fleshy eminenc

Cauda: tai

Cavity: a hollow space (or potential space) within the body or its organs

Cervix: means neck and is applied to the neck like portion of an organ (e.g. cervix of uterus

Chiasma: a crossing of fibers in the form of an X. Used primarily to describe nerve fibers

Commissure: a band of fibers which join corresponding right and left parts of a structure across the median plane

Corpus: means bod

Cortex: outer part, or rind, or some organs as distinguished from their inner part, or core usually called a medulla

Crest: a projecting ridge, especially one which on a bon

Crus: means a leg and is applied to a structure that resembles a leg or stal

Decussation: same as a chiasma. A crossing of fibers in the form of an X

Digitation: a finger like process of a muscle

Disc: a flat round structure usually applied to plates of cartilage in joints

Duct: a tube for the passage of fluid, especially secretions of glands. A ductule is a small duct

Epithelium: a layer of cells which forms the external surface of the skin, or which lines the cavities of the digestive, respiratory and urogenital organs, serous cavities, inner coats of blood and lymphatic vessels, gland and cavities within the brain. The epithelium of the skin is the epidermis. The epithelium of the digestive, respiratory and urogenital organs is moistened by a film of mucus and is known as the mucous coat. The epithelium lining bloods vessels is known as the endothelium. Serous cavities are lined by epithelium called mesothelium

Fascia: tissue which lies immediately deep to the skin known as subcutaneous tissue. It usually consists of a layer of connective tissue which contains fat, and of a deep and more fibrous layer which adheres to the surface of the underlying muscle and vessels. These layers are known as superficial and deep fascia respectively. Fascia surrounds every muscle, organ, vessel and nerve in the body

Fasciculusva small bundle. A term that is usually applied to collections of nerve fibers

Filum: literally mean a “thread”. This name is given to several thread-like structures such as the filum terminale, the lower extension of the pia mater of the spinal cord

Fold: a ridge formed where a membrane doubles back on itself

Folium: mean leaf. The plural “folia” is applied to the folds of the cortex of the cerebellum

Foramen: a hole, often in a bone or between adjacent bones

Fossa: a “ditch”, usually referring to a shallow depression or cavity

Fovea: a small pit or foss

Frenulum: a small fold of the mucous coat which limits the movement of the structure to which it is attached

Fundus: used to denote the widest part of a hollow organ

The Human Body: Terms of relation/position

Thursday, October 30th, 2008

I have high-hopes that blogging about this subject will assist in cementing this knowledge in my (already full) cranium:

Term 1 Term 2 Description
Superior (closer to the head) Inferior (closer to the feet) Horizontal plane
Posterior (dorsal) Anterior (ventral) Frontal or coronal plane medial
Medial (near the midline) Lateral (away from the midline) Sagittal plane
Proximal (closer to the origin of a structure) Distal (further from the origin of a structure) Origin of a structure
Superficial Deep Surface of body or organ
Median   Along the medial or mid-sagittal plane
Intermediate   Between two other structures
External Internal Refers to a hollow structure
Supine Prone Face/palm up lying on back, down when lying on front
Cephalad Caudad Towards the head or feet

Chocolate Yoga

Monday, October 27th, 2008

Friday evening, John and I attended an evening of chocolate yoga with Mark and Chantalle of Living Nutrition. For the first part of the evening, we learned about the health benefits of many live super-foods (courtesy of Mark) and enjoyed some raw chocolate, and then were drilled through a challenging asana practice by Chantalle. Ordinarily, I am less-than-thrilled with the use of wooden props as yoga accessories, but I vowed to keep an open mind and I found myself enjoying the practice. It was a perfect “date” night. I should have brought some of the chocolate home with me!

The Yogi and the Samurai

Thursday, October 23rd, 2008

When the love of your life recalls returns to his Samurai roots and you, yourself, feel strongly that you wish to be a yogi, where does the twain meet? Does it meet? Can it meet? They are both disciplined, noble pursuits. Should he wish to spend some time in Japan to further his dream, naturally I would be supportive. However, how much of one’s own dreams are to be sacrificed for the dreams of another? To me, the answer is clear. I cannot sacrifice my own dreams for the Samurai warrior, but perhaps a new dream can be manifested that we can share? Too often, I see couples that have sacrificed deeply for the love of their partner, and although this too would seem to be a noble, I don’t think it’s necessary. We are all the masters of our universe and of our destinies. I want to be a Yogi. I want to suck all of the marrow from the writings of the ancient Indian sages. I have read Paramahansa’s Autobiography of a Yogi so often that the book is falling apart and yet every time I open it, a new revelation strikes me. I wish to really understand the counsel of Krishna to Arjuna in the Bhagavad-Gita, and to be able to read Sanskrit. I want to have deep discussions over the writings of Pantanjali and explore many of the sutras. Can a Samurai and a Yogi have a future together? Perhaps with love, communication, and understanding, anything is possible.

Bones: The Ossuary System

Monday, October 20th, 2008

For me, personally, memorizing the bones of the skull has been the most challenging part of the ossuary system. Granted, I’m sure there are folks out there who would find the entire 200+ bones of the skeletal system to be a pickle to remember, but I’m choosing to focus on my own particular area of weakness.

Skull
  • Frontal Bone (front)
  • Occipital Bone (back)
  • Parietal Bone (across the top)
  • Temporal Bones (temples)
  • Sphenoid Bone (sides of the eye sockets)
  • Zygomatic Bones (cheeks)
  • Nasal (nose)
  • Lacrimal (around eye sockets)
  • Maxillae (upper jaw)
  • Mandible (lower jaw)

The Human Body: Planes

Wednesday, October 15th, 2008

Memorizing all of the bones in the human body came relatively easy for me. Learning the muscle groups was somewhat more challenging, but still fairly straightforward. The planes of movement of the human body, on the other hand, was somewhat of a shot in the dark for a person, such as myself, who has enough difficulty keeping their left and right straight. I suspect the piece-meal approach is going to work best for me in terms of digesting information that does not make natural sense.

Name Description
Frontal Separates the body into Anterior and Posterior parts
Median Separates the body into Right and Left parts
Horizontal Separates the body into Superior and Inferior parts
Sagittal Any plane parallel to the median plane
