The trachea is about 4 inches long, so we are almost out. I see our next respiratory structure up ahead. Let’s see if anyone can guess what it is. This structure is also known as the voice box and holds the vocal cords. If you guessed the larynx, you would be correct.
It is located in the left and right sides of the cerebrum. It is believed to be responsible for hearing, senses, language, learning, memory storage, auditory perception, speech, and complex visual perceptions. It is one of the four subdivisions of the cerebral cortex. Located in the rear of the cerebrum, it s one of the four major areas of the upper brain. It is primary responsible for vision and reading.
7. Spinal cord The mid dorsal line of the body. This has spinal nerves that leave the cord. Provide means of communication between the brain and spinal nerves. Also provides reflex actions.
Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli. a right lymphatic duct b.thoracic (left lymphatic)duct c.right brachiocephalic vein d.cisterna chyli . e. Determine the direction of blood and lymph movement between arterioles, blood and lymph capillaries, and venules. Starts as interstitial fluid then enters lymphatic capillaries then travels in lymphatic vessels to lymph nodes. The lymph ascends or descends to the left or right lymphatic duct.
Prone is the face down position and being dorsal is lying on the back. The sagittal plane is the vertical plane that divides the body into the left and right sides. Transverse is the horizontal plane that divides the body into the top and bottom sections. Superior is the upper part of the body while the bottom is the inferior. Distal is moving from the trunk of the body to the end of a limb and proximal is moving from the end of a limb toward the body.
The Abdominal cavity (AC) holds up most of the viscera that is with in the abdominal area. – No it does not hold up, it contains the majority of the viscera. Better to have started with the The Abdominal cavity is part of the ventral cavity system that was generated as the pre-embryo folded from the ‘flatten’ disc into the 3D embryo. Septa grow out and divided it into the thoracic and abdomenopelvic cavities The pelvic floor grow dividing off inferiorly the perineum. The abdomneopelvic boundaries are: Anteriorly the positerior surface of the abdominal wall.
Then we also have a top and bottom which is divided by the transverse plane. “The upper half of the body is the superior section, and the lower half is the inferior section” (Turley, 2011, p. 43); and when it comes to movement, moving to the top towards the head is moving the superior direction or cephalad direction. Moving down towards the tailbone is moving in an
The Cervical Portion of the internal carotid begins at the bifurcation of the common carotid, opposite the upper border of the thyroid cartilage, and runs perpendicularly upward, in front of the transverse processes of the upper three cervical vertebrae, to the carotid canal in the petrous portion of the temporal bone. It is comparatively superficial at its commencement, where it is contained in the carotid triangle, and lies behind and lateral to the external carotid, overlapped by the Sternocleidomastoideus, and covered by the deep fascia, Platysma, and integument, it then passes beneath the parotid gland, being crossed by the hypoglossal nerve, the Digastricus and Stylohyoideus, and the occipital and posterior auricular arteries. Higher up, it is separated from the external carotid by the Styloglossus and Stylopharyngeus, the tip of the styloid process and the stylohyoid ligament, the glossopharyngeal nerve and the pharyngeal branch of the vagus. It is in relation, behind, with the Longus capitis, the superior cervical ganglion of the sympathetic trunk, and the superior laryngeal nerve; laterally, with the internal jugular vein and vagus nerve, the nerve lying on a plane posterior to the
! a. The first cervical vertebra is called the axis. 5. The opening in vertebrae for the spinal cord is the !
The involuntary muscles are the ones that work without thinking about it like the heart and the stomach. The spinal cord has a long bundle of nerves inside of it and it has the vertebrae that protects them. The spinal cord and nerves, which are known as the nervous system that let the messages flow back and forth from the brain and the
