The transversus thoracic plane (TTP) can be found between the internal intercostal muscle and the TTM (Figure 1) and is the target for the TTPB.
What is transverse thoracic plane?
The thoracic plane, also known as the transthoracic plane or the plane of Ludwig is an artificial horizontal plane used to divide the mediastinum into the superior mediastinum and the inferior mediastinum.
What are the 4 body planes?
- median or sagittal plane.
- a parasagittal plane.
- frontal or coronal plane.
- transverse or axial plane.
What is the plane of the sternal angle?
The thoracic planeis a plane used to divide the mediastinum into a superior mediastinum and inferior mediastinum. This plane runs through the level of the sternal angle, (which is the joint between the manubrium and body of the sternum), between the intervertebral disc of T4 and T5.
Where is the horizontal plane?
aka transverse plane, a horizontal plane divides the brain into a superior and inferior portion. It is created by slicing the brain perpendicular to the long axis of the body, and thus parallel to the floor in a person that is upright. The black line above represents a horizontal plane.
What is another name for the transverse plane?
The transverse plane or axial plane (also called the horizontal plane or transaxial plane) is an imaginary plane that divides the body into superior and inferior parts. It is perpendicular to the coronal plane and sagittal plane.
What is a transverse plane in anatomy?
Axial Plane (Transverse Plane) – A horizontal plane; divides the body or any of its parts into upper and lower parts. Median plane – Sagittal plane through the midline of the body; divides the body or any of its parts into right and left halves.
What is the name of the upper portion of the sternum?
The manubrium(Latin for “handle”) is the broad upper part of the sternum. It has a quadrangular shape, narrowing from the top, which gives it four borders. The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium.
Where is sternal angle located?
The sternal angle, which varies around 162 degrees in males, marks the approximate level of the 2nd pair of costal cartilages, which attach to the second ribs, and the level of the intervertebral disc between T4 and T5. In clinical applications, the sternal angle can be palpated at the T4 vertebral level.
Where is 5th intercostal space?
The apex (the most inferior, anterior, and lateral part as the heart lies in situ) is located on the midclavicular line, in the fifth intercostal space. It is formed by the left ventricle. The base of the heart, the posterior part, is formed by both atria, but mainly the left.

What is the longitudinal plane?
A sagittal plane, also known as the longitudinal plane, is perpendicular to the ground and divides the body into left and right. … A coronal or frontal plane is perpendicular to the ground and divides the body into dorsal (posterior or back) and ventral (anterior or front) portions.
What are the 5 planes of the body?
They are the median plane, sagittal planes, coronal (frontal) planes and horizontal (transverse) planes (figure 2). Anatomical descriptions are also based on these planes. Anatomical planes. The median plane is the vertical plane that passes through the body longitudinally, dividing it into right and left halves.
What is distal anatomy?
Distal refers to sites located away from a specific area, most often the center of the body. In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist. Distal is the opposite of proximal.
What movements are in the transverse plane?
- Rotation: Moving the torso or a limb around its vertical axis.
- Pronation: Rotating the forearm or foot to a palm-side or foot-side down position.
- Supination: Rotating the forearm or foot to a palm-side or foot-side up position.
How many transverse planes exist in the human body?
A transverse plane (right) divides the body, or part of it, into top and bottom portions. Note that each of the three anatomical planes can be moved and still retain the name associated with its direction of orientation. Think of standing in the shallow end of a swimming pool with the water at about navel level.
What is the vertical plane?
Definition of vertical plane 1 : a plane that passes through a vertical line. 2 : a plane of perspective passing through the point of sight and perpendicular to the ground plane and to the picture.
What are the 3 planes of the body?
- Sagittal Plane: Cuts the body into left and right halves. Forward and backward movements.
- Frontal Plane: Cuts the body into front and back halves. Side-to-side movements.
- Transverse Plane: Cuts the body into top and bottom halves.
Which plane is most useful in the studies of organs in the human body?
The three planes most commonly used in anatomical and medical imaging are the sagittal, frontal (or coronal), and transverse plane.
Which body plane S would allow you to see the brain and the spinal cord?
Part (a.) In order for a plane to provide a view of both the spinal cord and the right lung, we would need to use the sagittal plane, specifically a parasagittal plane with the ‘line’ off centered towards the left, creating a larger right side portion to include the spinal cord.
Which plane separates the body into superior and inferior portions?
Explanation: A coronal section (frontal plane) describes a plane that divides the body into ventral (front) and dorsal (back) sections. A transverse plane is a horizontal plane that divides the body into superior and inferior parts.
Where are the 8th and 9th ribs located?
These ribs, known as true ribs, also connect to your spine in the back. The 8th, 9th, and 10th rib pairs don’t connect directly to your sternum, but they are connected to each other by cartilage that attaches to the costal cartilage of the 7th rib pair. These ribs also attach to your spine in the back.
Why is sternal angle important?
Clinical Significance The sternal angle is an important clinical landmark for identifying many other anatomical points: It marks the point at which the costal cartilages of the second rib articulate with the sternum. This is particularly useful when counting ribs to identify landmarks as rib one is often impalpable.
What rib attaches to the sternal angle?
The second rib attaches to the sternum at the sternal angle. Since the first rib is hidden behind the clavicle, the second rib is the highest rib that can be identified by palpation. Thus, the sternal angle and second rib are important landmarks for the identification and counting of the lower ribs.
What bone is located just below the urinary bladder?
The pubic symphysis is a secondary cartilaginous joint between the left and right superior rami of the pubis of the hip bones. It is in front of and below the urinary bladder. In males, the suspensory ligament of the penis attaches to the pubic symphysis.
What is the end of the breastbone called?
The smallest and most inferior region of the sternum, the xiphoid process, begins life as a region of flexible hyaline cartilage attached to the end of the body of the sternum. The xiphoid process slowly ossifies throughout childhood and adulthood until around age 40 when all of its cartilage is replaced by bone.
What organs are under the sternum?
- The medulla is the inside part of the thymus.
- The cortex is the layer that surrounds the medulla.
- The capsule is the thin covering over the outside of the thymus.
Where is the 8th rib?
In the anterior thorax, the first 7 pairs of ribs are attached to the sternum or breastbone by cartilage. The lower 5 ribs do not attach to the sternum. The 8th, 9th, and 10th ribs are attached to each other by costal cartilage.
What are floating ribs?
Floating ribs can also be called the vertebral ribs. They don’t ventrally bind with the sternum but are only attached to the vertebral column. They are the very last two groups of ribs, the 11th and 12th pair, are known as the floating ribs.
Where is 4th intercostal space?
The location of the 4th and 5th intercostal space is related to the length of the sternum. It is 77% of the sternal length that measures 15cm for the 4th intercostal space. The position of the V1 and V2 electrodes decreases to 57% when the sternal length is 26cm.
Is cross section same as transverse?
Sections through or parallel to either the sagittal or coronal (also called frontal) plane are longitudinal. A transverse section is perpendicular the anterior-posterior axis and is also called a cross section .
What is transverse and longitudinal section?
Longitudinal section runs through the anterior posterior axis, whereas the transverse section goes between lateral ends. … Usually, the number of possible transverse sections is higher than the number of possible longitudinal sections to be made through an organ or organism.
