Where is the axillary line located?

Where is the axillary line located?

Within the armpit, the axillary line is also situated between the anterior axillary fold, formed by the muscles of the chest (pectoralis), and the posterior axillary fold, formed by two major muscle of the upper back (the latissimus dorsi and teres major).

What is the sternal line?

n. A vertical line corresponding to the lateral margin of the sternum.

What is located right of the Midsternal line at the level of the 5th intercostal space Midclavicular line *?

Mitral area
Tricuspid area: Over the lower-left sternal border. Mitral area: At the left 5th intercostal space at the midclavicular line.

At what distance from the mid sternal line is the PMI considered indicative of left ventricular hypertrophy or enlargement?

A PMI lateral to the midclavicular line or below the sixth intercostal space suggests left ventricular enlargement. If the PMI is greater than 2 cm in size there is likely left ventricular hypertrophy or dilation.

What is axillary line and its types?

The axillary lines are the anterior axillary line, midaxillary line and the posterior axillary line. The anterior axillary line is a coronal line on the anterior torso marked by the anterior axillary fold. The posterior axillary line is a coronal line on the posterior torso marked by the posterior axillary fold.

What’s the Midclavicular line?

Medical Definition of midclavicular line : an imaginary line parallel to the long axis of the body and passing through the midpoint of the clavicle on the ventral surface of the body.

Where is the sternal angle?

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.

Why does the area around my sternum hurt?

Costochondritis is the most common cause The most common cause of sternum pain is a condition called costochondritis. This occurs when the cartilage that connects your ribs to your sternum becomes inflamed. Symptoms of costochondritis include: sharp pains or aches on the side of your sternum area.

Where is the 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.

Where can you best hear the apical impulse?

Measuring the apical pulse The doctor will place a stethoscope on the left side of the breastbone, over the apex of the heart. They can also feel the apical pulse at the point of maximal impulse (PMI). The PMI is in the space between the fifth and sixth ribs on the left side of the body.

Why apex beat is palpable?

This is usually due to a thick chest wall, emphysema, pericardial infusion, shock or dextrocardia. Rolling the patient into the left lateral position may enable the apex beat to be palpated (Scott and MacInnes, 2006). The location and the character of the apex beat should be noted.

What is the normal distance from the midsternal line?

1. 2. A set distance from the midsternal line (the traditional upper limit of normal is 10 cm) 3.

How big is the PMI of the midsternal line?

The PMI normally has a diameter of about 2 cm and is located at the intersection of the fifth intercostal space and midclavicular line (within about 10 cm of the midsternal line); use the pads of the fingertips to locate the PMI. The PMI may be more central in tall, thin individuals.

Where is the midclavicular line in the heart?

Midclavicular line is a vertical line running from a spot in the middle of the clavicle to the point where it meets the hip bone. One point of interest along the midclavicular line is the heart. When listening for a heartbeat, this line can be used as a reference to find a location for listening.

Is the midsternal line a good predictor of enlarged heart?

Using a point 10 cm from the midsternal line to define the displaced impulse is not a useful predictor of the enlarged heart (positive LR not significant, negative LR = 0.5; see EBM Box 36-1 ), probably because the 10-cm threshold is set too low. (The midclavicular line usually lies 10.5 to 11.5 cm from the midsternal line.
