Cavity is a hollow space surrounded by bones and muscle. | Carnial cavity in the skullSpinal cavity is the backboneThoaric cavity is in the chestMediating is the middle where the heart is or tracheaAbdominal cavity is in the abdomen or bellyPelvic cavity is in the area of the pelvis bone | Quadrant and regions | The human body can be studied by regions and quadrants. Right upper quadrant (RUQ) * Left upper quadrant (LUQ) * Left lower quadrant (LLQ) * Right lower quadrant (RLQ) * Cervical area * Thoracic area * Lumbar area * Sacral area * Coccygeal area | * oThe 9 regions include: * Right hypochondriac region * Epigastric region * Left hypochondriac region * Right lumbar region * Umbilical region * Left lumbar region * Right inguinal or iliac region * Hypogastric region * Left inguinal region | Anatomy and physiology | Human body can be studied by its structures and the anatomy of its structures as well as its functions. | Anatomy-Apart from and process of cutting Physiology- the study of function
The skeletal system includes all of the bones and joints in the body. Each bone is a complex living organ that is made up of many cells,, protein fibers, and minerals. The skeleton provides support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachment points for the rest of the body allowing movement. The skull is composed of 22 bones that aid in the support and movement, and protection of the brain.
Pamela Figus Lab 8: Chicken Muscle Dissection Purpose To determine the musculoskeletal comparisons of chicken wing to human upper extremity. Hypothesis The muscles and tendons of the chicken wing will react in the same manner as that of a human upper extremity. Materials & Methods Materials: List your materials used for your lab here. Methods: Part A: Arrange your wing so that the joints match the image below. Remove the skin as follows: At the cut end of the upper wing, slip the tip of the scissors between the skin and the muscles underneath.
The cerebrum is composed of two symmetrical hemispheres which are separated by a deep midline sagittal fissure which is deemed the longitudinal fissure, which contains a fold of dura matter, the flax cerebri. In the depths of this longitudinal fissure is a great commisure, the corpus callosum which connects the two hemispheres. The hemispheres are separated from the cerebellum by a fold of dura matter termed the tentorium cerebelli. The hemispheres have both deep fissures or sulci and raised areas or a gyrus, which allow for further division of the cortex. The main sulcus is the central sulcus, which indents the superior-medial surface of each hemisphere.
The Transversus draws the sides of the tongue medially. The Verticalis interdigitates with the Transversus at ninety-degree angles, running parallel to both the sagittal and coronal planes, and across the transverse plane, allowing the tongue to become narrower top to bottom in the coronal and sagittal planes. The extrinsic muscles, those that
The intermediate portion or infraorbital head arises from the lower margin of the orbit immediately above the infraorbital foramen, some of its fibers being attached to the maxilla, others to the zygomatic bone. Its fibers converge, to be inserted into the muscular substance of the upper lip between the angular head and the Caninus. The lateral fibers, forming the zygomatic head, arise from the malar surface of the zygomatic bone immediately behind the zygomaticomaxillary suture and pass downward and medialward to the upper lip. Its main function is to elevate the upper lip. Effect on complete denture On maximum contraction of the Quadratus Labii superior the upper lip is pulled upward raising the upper lip dragging the labial gingivomucosal sulcus superiorly.
There are two parts to this ligament; superior and inferior. Superior acromioclavicular ligament this ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the lateral end of the clavicle and the adjoining part of the upper surface of the acromion. Inferior Acromioclavicular Ligament This ligament is somewhat thinner than the preceding, it covers the under part of the articulation, and is attached to the adjoining surfaces of the two bones. The coracoacromial ligament runs from the coracoid process and the acromion. The coracoacromial ligament is a strong triangular band, extending between the coracoid process and the acromion.
List the general characteristics of vertebrates. The general characteristics of vertebrates are two unique features of vertebrates: a skull and a backbone. The skull forms a hard case for the brain. The backbone is composed of a series of skeletal segments called vertebrae (singular, vertebra), which enclose the nerve cord. 4.
The human body has 206 bones which are organized in the skeleton. It functions as a protection of vital organs, forms the framework of the body, and supports vital body functions, such as physical movement, as well as communication. The skull encases the soft tissue in the human brain, the rib cage and sternum, shield the heart and lungs from the surrounding environment, and the pelvis safely houses our internal organs. Humans have an endoskeleton which is inside the body, and is split into two main divisions, the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones and comprises the skull (facial bones and cranial bones), hyoid bone, , vertebral column, auditory ossicles and the thorax (the sternum and the rib bones form the thorax).
