Week 5 Flashcards
What is the location and structural origin for the thoracic duct?
L2 from the cisterna chyli.
What parts of the body will the right lymphatic duct drain?
The right side of the head, neck, and thoracic parietal wall, as well as the right upper extremity, right lung and convex (diaphragmatic) surface of the liver.
What are examples of aggregate lymph nodules?
The tonsils and Peyer’s patches of the small intestine.
What is the function of lymph nodules?
Perpetuation of the lymphocyte cell line and to aid in the immune response.
What is the function of lymph nodes?
They primarily filter lymph but also are involved in lymphocytopoiesis and they do participate in the immune response.
What muscles attaches to the anterior arch of C1?
Longus colli.
What is the morphology of the superior articular facet of C1?
They are elliptical, closer together in front and often demonstrate an elevation subdividing the facet surface into two separate surfaces.
What is the orientation of the inferior articular facet of C1?
Backward, medial, downward (BMD).
What is the name of the rounded elevation on the medial aspect of the lateral mass of C1?
Tubercle for the transverse atlantal ligament.
What muscles attach to the lateral mass of C1?
Levator scapula, splenius cervicis and rectus capitis anterior.
What is the distance from the posterior tubercle of the posterior arch to the skin in each gender?
Males: about fifty millimeters; females: about thirty-seven millimeters.
What attaches to the posterior tubercle of the posterior arch of C1?
Rectus capitis posterior minor muscle and ligamentum nuchae.
With regard to ossification of the posterior atlanto-occipital ligament, what is the gender bias, bone classification, amount of ossification and gender percent in the population?
Male, accessory bone, complete ponticulus posticus, fifteen percent; female, accessory bone, partial ponticulus posticus, twenty six percent.
What muscles attach to the transverse process of C1?
Rectus capitis anterior, rectus capitis lateralis, middle scalene, levator scapula, splenius cervicis, obliquus capitis superior, obliquus capitis inferior and intertransversarii muscles.
What is the gender variation for measurements of the transverse diameter for C1?
Males: 78 millimeters and females: 72 millimeters.
