The pectoralis minor is lengthened during glenohumeral external rotation, scapular upward rotation, and scapular posterior tilting.20 The pectoralis minor originates in the superior margins of the outer surfaces of the third, fourth and fifth ribs near the cartilage. It inserts on the medial border, superior surface of the coracoid process of the scapula. The pectoralis minor is innervated by the medial pectoral with fibers from a communicating branch of the lateral pectoral. Its actions include tilting the scapula anterior while supporting ribs during inspiration.12 Tightness of this muscle has been shown to increase scapular anterior tilt and internal rotation. 21 J. H. Lee et al.
In 1949 Testut and Latarget further modify the descripton by concluding that the Sacroiliac joint contain a freely mobile ventral aspect and an ossified dorsal aspect. They dubbed the Sacroiliac joint as ‘diaarthro-amphiarthrosis’ that is a joint that has characteristics of both a freely mobile joint and an ossified
(See p. 45 of the FPDG.) Adrenal glands – In the fetal pig, the adrenal glands are found near the aorta towards the cephalic end of the kidneys, instead of on top of the kidneys as is the case in humans. (See p. 45 of the FPDG.) Quiz: Like humans, the adrenal glands of the fetal pig are retroperitoneal. What other abdominal organs are retroperitoneal?
They both have c-shaped cartilage. There are no cartilage structure on the bronchioles. The main function of the bronchi and bronchioles is to carry oxygen from the trachea into the lungs. Smooth muscle is located within the walls to help control airflow into the lungs. At the end of each bronchiole is alveoli.
In this instance, specific focus and attention is necessary to be drawn to the perineum. The perineum is the part of the trunk that lies caudal to the pelvic floor.1 The perineum contains the perineal body (also known as the central perineal tendon) and the deep and superficial transverse perineal muscles. The perineal body is the site along which the tendineus fibres from the two sides of the perineal muscles decussate each other across the midline. This muscle arrangement allows simultaneous contraction of the perineal muscles, which allow the perineal muscles to stretch and elevate as
During the development of the mouth palate, two palate formations can be differentiated, namely the Primary palate and the Secondary palate. The purpose of the palates is to provide a division between the oral and the nasal cavities. Primary palate: Between the embryological period of week six and seven, formation of the primary palate takes place. The primary palate develops due to the merging of the medial and lateral nasal prominences with each other, and then the merging of the maxillary and the medial nasal prominences which pinches an epithelium layer which gives rise to the superior nasal epithelium and the inferior oral epithelium. The core of the primary palate is formed by the two epithelium layers mentioned above.
By looking at the back of the skull and analyzing the morphology of the occipital and nuchal region the shape of occipital and nuchal region can be determined. When determining canine size and diastema, one should analyze and compare the canine to other teeth and the space between the canine and the premolars. The chin or mandibular symphysis can be analyzed by looking at the profile of the mandibule. The shape of dental arcade can be determined by looking at the skull from a ventral view and analyzing the shape that the upper teeth generate. The dentition can be determined by analyzing the size of the overall teeth with the size of the overall facial size.
The brainstem is located underneath the limbic system is the brain stem. The midbrain includes the tectum and tegmentum. The brain stem is made up of the midbrain, pons, and medulla. The midbrain is the rostral part of the brain stem. The pons are a part of the metencephalon in the hindbrain.
