The brachial plexus is a network of spinal nerves. Spinal nerves carry information from peripheral sensory receptors to the spinal cord (of the central nervous system)‚ and then carry information back from the central nervous system to effector muscles and glands. The brachial plexus carries out these functions in the pectoral girdle and upper limbs. Specifically‚ nerves of the brachial plexus aid in innervation of the muscles of the upper limbs (with the exception of the trapezius and the levator

Nervous System The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. Animals with backbones and spinal columns have a central and a peripheral nervous system. The central nervous system is made up of the brain‚ spinal cord and retina. The peripheral nervous system consists of sensory neurons‚ ganglia and nerves that connect to one another and to the central nervous system. (https://campus.ctuonline.edu/courses/BIO110/p1/hub1/12547

calcium is needed for healthy nerve functioning. The skeletons key components are ligaments‚ the axial skeleton; this consists of the skull‚ spine‚ ribs‚ and breast bone. The appendicular skeleton which consists of limb bones‚ shoulders and hips. Muscular Muscles work with the skeleton‚ which provides a range of pulling forces‚ powerful to intricate‚ for movement. Involuntary muscles work automatically in order to control internal processes‚ such as blood distribution and digestion. Muscles particularly

Description Biology 111 is a study of the structure and function of the human body. The course covers in detail the human body from its biochemical and sub cellular aspects through tissues. Special emphasis is given the integumentary‚ skeletal‚ muscular‚ nervous‚ and endocrine systems. The lecture and laboratory are correlated to provide an overview of the interrelationships of normal human anatomy and physiology. Biology 111 meets the general education requirement for group II-science. b. Learning

Normally‚ you may see the pulsations from the aorta beneath the skin in the epigastric area‚ particularly in thin persons with good muscle wall relaxation. b. Marked pulsation of aorta occurs with widened pulse pressure (e.g.‚ hypertension‚ aortic insufficiency‚ thyrotoxicosis) and with aortic aneurysm. c. lateral pulsation with aortic aneurysm pushes the examiner’s two fingers apart. 2.

Richard A. Andersen HCA 220 Week 2 Assignment Professor Danielle Griffin January 22‚ 2014 There are seven organizational approaches to examining the human body‚ each way being significant in that it allows for the human body to be examined from a specific point of view‚ helps to understand the complexity of each working system‚ and provides information that is unique to each approach‚ by organizing the body in a logical and sensible way (Turley‚ 2011. P. 41). These seven systems are body
