Brain Function Brain Structures and Functions Work Sheet Christine Bedgood PSY/340 6/3/2013 Jill Bean 1-Basal ganglia- The basal ganglia form a set of interconnected nuclei in the forebrain. The basal ganglia receive a large amount of input from cerebral cortex, and after processing, send it back to cerebral cortex via thalamus. Scientist believe this Basal ganglia is involved with the function of learning. (Pinel, 2009) 2. Corpus

molecule of stable chromosomal DNA. Prokaryotes lack mitochondria and chloroplast. Instead, processes such as oxidative phosphorylation and photosynthesis takes place across the prokaryotic cell membrane. However, prokaryotes do possess some internal structures, such as prokaryotic cytoskeletons. They also have a larger surface area to volume ratio giving them a higher growth rate and as a consequence, a shorter generation time than eukaryotes. Most prokaryotes are between 1nanometer and 10nanometer

Describe the gross structure and main functions of all major body systems (P5) Reproductive systems Male (Harvard-wm.org, 2014) The male reproductive system is made up of the scrotum, testes, epididymis, spermatic cords, vas deferens, seminal vesicles, ejaculatory duct, urethra, prostate, cowper glands, the penis and the semen. The scrotum is a sac like structure in which the testes are located, it is found in the pubic region and its job is to regulate the temperature of sperm by

The human penis is an external male intromittent organ that additionally serves as the urinal duct. The main parts are the root (radix); the body (corpus); and the epithelium of the penis including the shaft skin and the foreskin covering the glans penis. The body of the penis is made up of three columns of tissue: two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The human male urethra passes through the prostate gland, where it is joined by the ejaculatory

Introduction This essay will consider the structure and function of the 11 systems within the human body. It will detail the interrelationship between the nervous system and the musculoskeletal system and between the circulatory system and the lymphatic system. It will then explain the roles of the circulatory and lymphatic systems in the immune response and the role of hormones in metabolism. Human Body Systems The human body is made up of 11 separate but interconnected systems (Sherwood, 2007)

Structure-functionalism relies upon an "organic" analogy of human society as being "like an organism," a system of interdependent parts that function for the benefit of the whole. Thus, just as a human body consists of parts that function as an interdependent system for the survival of the organism, society consists of a system of interdependent institutions and organizations that function for the survival of the society. Relying upon the successes of biologists in understanding the human body

Test 2 1. Cell Body: (Or soma) is a relatively large, egg-shaped structure that provides fuel, manufactures chemicals, & maintains the entire neuron in working order. Dendrites: Branchlike extensions that arise from the cell body; they receive signals from other neurons, muscles, or sense organs & pass these signals to the cell body. Axon : A single threadlike structure that extends from, & carries signals away from, the cell body to neighboring neurons, organs, or muscles. Myelin Sheath: Looks

capable of independent functioning. All cells start life with a plasma membrane, cytoplasm, organelles, and DNA. Cells vary in size and also in what job function they have. Cells are complex but highly organized. They contain a number of internal structures. A cell’s plasma membrane is the cell’s outer membrane. It separates the cell from the external area. The cell membrane surrounds the outside of both Eukaryotic and Prokrayotic cells. It is made of a double layer of phospholipids and controls

The latest period of human evolution begins with the arrivals of Homo sapiens. Today Homo sapiens are known to be the modern humans. The structure of the Homo sapiens is unique among any other Homo species, because of changes in the brain size and skull. The average cranial capacity of Homo sapiens is about 1,300 cubic centimeters making it the largest brain size from other Homo species. The modern skull has a short base and a high braincase. The Homo sapiens first appeared in Africa about 200,000

different organisms living in the depths of the ocean each with different life styles, structures, adaptations and ways of hunting. It is certain that one of the most interesting and dangerous of these organisms are the killer cone snails which look harmless at first but can become a death machine in just a few seconds. The cone snails have one of the most toxic poisons in the world, even two drops are enough to kill a human in just a few minutes. Despite the fact that snails are one of the slowest animals
