What are the directional terms of the human body?
Directional terms and body planes
| Anterior | In front of or front |
|---|---|
| Ventral | Towards the front of the body |
| Dorsal | Towards the back of the body |
| Distal | Away or farthest away from the trunk or the point of origin of the body part |
| Proximal | Closer or towards the trunk or the point of origin of the body part |
What are the 3 body planes?
There are three planes commonly used; sagittal, coronal and transverse.
How do you remember the directional terms of the body?
An easy way to remember this is to hold a pistol in your hand, and remember this phrase: the pistol is distal to your upper arm. Your fingers (phalanges) would be distal to your wrist bones (carpals). Your femur bone in your upper leg would be proximal to your ankle bones (tarsals).
What are the two orientations that a body can be in while in anatomical positions?
Anatomical Orientation and Directions
- Superior/Inferior–Equivalent to above and below when moving along the long axis of a body in anatomical position.
- Proximal/Distal–Equivalent to near and far.
- Medial/Lateral–Equivalent to towards the middle or towards the edge.
- Anterior/Posterior–Equivalent to the front and back of a body in anatomical position.
What is the difference between proximal and distal?
In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. Distal is the opposite of proximal. Distal refers to distance, while proximal indicates proximity.
What does proximal to distal mean?
Proximal and Distal They describe the position of a structure with reference to its origin – proximal means closer to its origin, distal means further away. Examples: The wrist joint is distal to the elbow joint.
What is the difference between proximal and distal convoluted tubule?
A proximal convoluted tubule drains filtrate away from a renal corpuscle. A loop of Henle descends into the medulla, makes a hairpin turn, and returns to the cortex. The distal convoluted tubule passes near to the original corpuscle (at the juxtaglomerular apparatus), then leads to a collecting duct.
What is the main function of distal convoluted tubule?
A distal convoluted tubule connects to the collecting duct system that fine-tunes salt and water reabsorption and plays a major role in acid–base balance. The initial segment of the collecting duct, the cortical collecting duct, takes off from the distal convoluted tubule in the cortex.
How can you tell the difference between a PCT and DCT?
Proximal Convoluted Tubule (PCT) receives primary urine from glomerulus. Distal Convoluted Tubule (DCT) receives urine from the glomerulus. PCT regulates excretion of urine by absorbing excess water from primary urine. In DCT, water and salts are secreted.
What is the main function of DCT?
Although the DCT is the shortest segment of the nephron, spanning only about 5 mm in length in humans (1), it plays a critical role in a variety of homeostatic processes, including sodium chloride reabsorption, potassium secretion, and calcium and magnesium handling.
What hormones affect the function of the DCT?
They are produced by endothelial cells of the renal blood vessels, mesangial cells, and cells of the DCT. Hormones stimulating endothelin release include angiotensin II, bradykinin, and epinephrine.
What is pct nephron?
The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman’s capsule to the beginning of loop of Henle. It can be further classified into the proximal convoluted tubule (PCT) and the proximal straight tubule (PST).
What is the full form of PCT?
The Full Form of PCT is Patient Care Technician, and it is an essential career in the medical industry. It requires a candidate to pass an examination if they’d like to study the course and practice it in the future.
What does PCT stand for in school?

What is pct blood?
Procalcitonin (PCT) is a blood test frequently performed if there is a suspicion of bacterial sepsis, a severe systemic infection that can become life-threatening. The procalcitonin test is an easy way to make the diagnosis quickly and potentially save lives.
What if PCT is low?
Low levels of procalcitonin in a seriously ill person may indicate a low risk of developing sepsis and progression to severe sepsis and/or septic shock but do not exclude it. Low levels may indicate that the person’s symptoms are due to a cause other than a bacterial infection, such as a viral infection.
What is a normal PCT level?
PCT is normally less than 0.05 ng/ml (equivalent to less than 0.05 ug/L) in healthy individuals. note however that normal levels do not exclude infection. All results should be interpreted in the context of the patient’s clinical history.
Why PCT test is done?
why is pct done? PCT is generally carried out to eliminate any cervical-related abnormalities if the female partner is unable to conceive. Doctors suggest the post coital test after it has been established through other tests that the female is ovulating well and the semen analysis of the male is normal.
