From C4–5, the thyroid cartilage [10] From C6–7, the cricoid cartilage [10] At C6, the oesophagus becomes continuous with the laryngopharynx and also where the larynx becomes continuous with the trachea. It is also the level where the carotid pulse can be palpated against the transverse process of the C6 vertebrae.
The target of C5 convertase is complement protein C5. C5 is a two-chain (α, β) plasma glycoprotein (Mr = 196,000). C5 and C3 have similar structure. However, C5 does not appear to contain the internal thiol ester group reported for C3 and C4. C5 has relatively few disulfide bonds.
In other words, the facet joint between C4 and C5 vertebral segments is innervated by the C4 and C5 medial branch nerves. However, there are two exceptions: The facet joint between C2 and C3 is innervated by the third occipital nerve and the C3 medial branch nerve. The facet joint between C7 and T1 is innervated by the C7 and C8 medial branch ...
The thyroid cartilage is found between the levels of the C4 to C5 vertebrae. The oblique line is a line on the thyroid cartilage. It marks the upper lateral borders of the thyroid gland. Two muscles originate along the line, the thyrohyoid muscle and inferior pharyngeal constrictor. The sternothyroid inserts along the line. Thyroid cartilage
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
C4 – Over the acromioclavicular joint. C5 – On the lateral (radial) side of the antecubital fossa, just proximally to the elbow. C6 – On the dorsal surface of the proximal phalanx of the thumb. C7 – On the dorsal surface of the proximal phalanx of the middle finger. C8 – On the dorsal surface of the proximal phalanx of the little finger.
In humans, the right and left phrenic nerves are primarily supplied by the C4 spinal nerve, but there is also a contribution from the C3 and C5 spinal nerves. From its origin in the neck, the nerve travels downward into the chest to pass between the heart and lungs towards the diaphragm.
The cervical spinal nerve 5 (C5) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 5 (C5). It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the ...
