Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.
The skin over your belly is cleaned. An incision is made in your belly. The tissue, blood vessels, and organs in your belly are carefully looked at and checked for problems. Tissue samples (biopsy) may be removed and sent to a lab for study.
Answer:
The answer would be Active and Passive ROM
A typical memory aid that helps in remembering the order in which sound travels from the peripheral to the central components of the auditory pathway would be E.C.O.L.I.M.A.
Sound (high or low-frequency sounds) at first gets to the hair cells of the Ear receptors (E) in Cochlea and cranial nerve number 8 (CN VII), then it gets to the Cochlear nuclei (C) which are cells dedicated to these high or low-frequency sounds.
At the Superior Olivary nucleus (O) sound is localized before it gets to the midbrain - Lateral lemniscus (L) and Inferior colliculus (I). The inferior colliculus receives auditory nerve fibers from ipsilateral superior olivary nuclei through the lateral lemniscus.
Sounds then get to the thalamus at the Medial geniculate body (M) which receives nerve fibers from the inferior colliculus; eventually sounds then get to the auditory cortex.
In summary, ECOLIMA is an easily understandable mnemonic device to help remember how sound waves move from the external ears to the auditory nerves and cortex.
