Is the head inferior or superior to the feet?
A body part that is above another part or closer to the head. Ex: Your head is superior to your feet. A body part is below another part or toward the feet.
Is to cephalic as inferior is to caudal?
Cephalic refers to the head of the embryo, while caudal refers to the tail (inferior) end. Cranial is often used instead of cephalic when describing a location of one structure relative to another.
What is cephalic and caudal?
Cephalic: relative term meaning nearer to the head (ex: collar bone is cephalic to the sternum). Caudal: relative term meaning nearer to the tail (ex: sternum is caudal to the collar bone). Anterior: toward the front of the body (ex: the nose is anterior to the brain).
Which body part is most cephalic?
- The cephalic region (head) or cranial region (skull) is at the top of the body and visible from the front and rear.
- The cervical region (neck) starts below the head, ends at the thorax, and is visible from the front and rear from below the head to the shoulders.
What is the difference between cranial and caudal?
Cranial/Caudal: Cranial — directed toward the cranium (brain case) [neck, trunk, tail, limbs]. Caudal — directed toward the tail (& beyond) [head, neck, trunk, tail, limbs].
What is meant by caudal direction?
72 The neural arch slope is measured relative to the vertical. Vertical is defined as being orthogonal 73 to the horizontal. That in turn is defined by the cranial–caudal (= anterior–posterior) axis.
What does caudal mean?
Pertaining to the tail
What part of the body is caudal?
Directional Terms Inferior or caudal – away from the head; lower (example, the foot is part of the inferior extremity). Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body).
What is the caudal end?
Caudal (anatomical term) (from Latin caudum; tail), used to describe how close something is to the trailing end of an organism. Caudal artery, the portion of the dorsal aorta of a vertebrate that passes into the tail. Caudal cell mass, the aggregate of undifferentiated cells at the caudal end on the spine.

What does Cephalad and Caudad mean?

What is Cephal?
Cephal- is a combining form used like a prefix meaning “head.” It is often used in medical and scientific terms.
Which direction is Cephalad?
adjective Referring to the direction of the head; towards the head.
What does Sinistrocardia mean?
n. The displacement of the heart to the left.
What does Sinistro mean in medical terms?
Combining form denoting left, toward the left.
What does the prefix Tachy mean in medical terms?
Tachy- = prefix denoting fast, rapid. Tachypnoea = rapid breathing.
What does the prefix Dextro mean?
Dextro-: Prefix from the Latin word dexter, meaning ‘on the right side. ‘ For example, a molecule that shows dextrorotation is turning or twisting to the right.
What is Dextro and Laevo?
The prefix levo comes from the Latin word laevo. It means “on the left side” or “to the left.” We see these terms when we talk about chiral molecules rotating the plane of polarized light. If the plane of polarized light is rotated counterclockwise (to the left), the molecule is levorotatory (l).
What does Levo and Dextro mean?
levo-: From the Latin “laevus” meaning on the left side. For example, a molecule that shows levorotation is turning or twisting to the left. The opposition of levo- is dextro- (from the Latin “dexter” meaning on the right side) so the opposite of levorotation is dextrorotation.
What does Dextro mean in chemistry?
dextro- a combining form meaning “right,” used in the formation of compound words: dextrorotatatory. Chemistry. a combining form meaning “turning clockwise”: dextroglucose.
What is the symbol of Dextrorotatory?
An optically active compound that rotates the plane of plane-polarized light clockwise, observed toward the light leaving the compound, is said to be dextrorotatory (symbol: d or +).
How do I know if I have Dextrorotatory or Levorotatory?
If a compound rotates plane polarized light in the clockwise (+) direction, it is said to be dextrorotatory, while if it rotates light in the counterclockwise (-) direction it is levorotatory.
What does enantiomer mean?
Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other. Enantiomers are in every other respect chemically identical.
What causes chirality?
The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers.
What is enantiomer with example?
Enantiomers are chemical isomers that are non-superimposable mirror images of each other. Moreover, these types of stereoisomers can be considered as mirror images of each other. A common example of a pair of enantiomers is dextro lactic acid and laevo lactic acid, whose chemical structures are illustrated below.
How do you know if something has an enantiomer?
ENANTIOMERS ALWAYS HAVE OPPOSITE R,S DESIGNATIONS….It’s (S)-2-butanol.
- Let’s say you’ve got a molecule with two stereocenters and the configuration is (R,R).
- If you’ve got a chiral molecule with two stereocenters and the configuration is (R,S), the enantiomer will have the (S,R) configuration.
