Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating‚ processing‚ and coordinating Sensory data and motor commands the central nervous system‚ which interprets sensory input and carry information to maintain homeostasis. CNS can’t be regenerate because a CNS consists of the spinal cord that mean if it’s break the spinal cord is break also. The peripheral nervous system consists of the nerves

Muscle and Nerve Preparation Preparation of Ringer ’s solution Dissolve 6.5 g of sodium chloride (NaCl)‚ 0.14 g of potassium chloride (KCl)‚ and 0.20 g of sodium bicarbonate (NaHCO3) in 800 mL of distilled water. Also‚ dissolve 0.16 g of hydrated calcium chloride (CaCl2.2H2O) and 0.39 g of hydrated magnesium sulfate (MgSO4.7H2O) in 100 mL of distilled water. Add the 100 mL cautiously to the 800 mL‚ stirring vigorously. Then make the final volume equal to 1 liter by adding more distilled water

The job of the central nervous system is to process and send information to the peripheral nervous system. The nervous system consists of the brain‚ spinal cord and a complex network of neurons. The central nervous system is responsible for receiving‚ sending and interpreting information from the whole body. The nervous system also monitors and coordinates internal organ functions and responds to external changes as they occur. The two main organs of the central nervous system are the brain and

Advance Preparation—ATP Muscle Kit 1. Order the ATP muscle kits (Carolina) to be delivered no more than seven days before the lab. One kit provides generously for eight students. Extra vials of the chemical solutions can be ordered separately (Carolina) and will reduce waiting time. Just before the lab begins‚ cut the muscle bundles into 2-centimeter lengths and place in a petri dish in the accompanying glycerol. 64 Exercise 11 R E V I E W S H E E T NAME ____________________________________

Articular cartilage - is a white‚ smooth tissue which covers the ends of bones in joints. Periosteum - is a fibrous sheath that covers bones. It contains the blood vessels and nerves that provide nourishment and sensation to the bone. Cortical bone - forms the outer shell of all bone and also the shafts in long bones. Trabecular bone - is the tissue that makes up the interior of bones. Epiphyseal plate - is an area at the long

Neurons and nervous systems Communication around the body Neurons - the basic building blocks of the nervous system‚ soecialised to communicate info around the body Three different types of neurons sensory neurons (afferent) : transfer info from the body to the brain Motor neurons (efferent) : transmit info from brain to the body Interneurins : communication b/w sensory and motor neurons Structure communication with a neuron Communication within neurons is an electrochemical process

-We have 2 parts in our nervous system: The central nervous system (CNS) is the nerves in our brain and spinal chord. The peripheral nervous system (PNS) is a network of nerve cells in the rest of our body. -Our nervous system detects stimuli and allows us to react to them. -Stimulus: a change‚ action or occurrence in the environment that can cause an organism to respond. Eg. Light‚ noise‚ pressure… How do we detect stimuli? -We have sensory organs that detect particular stimuli eg. Skin What

The central nervous system (CNS) is that portion of the vertebrae nervous system that is composed of the brain and spinal cord. Together with the peripheral nervous system (PNS)‚ the other major portion of the nervous system‚ the CNS coordinates the body’s interaction with the environment. The CNS is contained within the dorsal cavity‚ with the brain in the cranial subcavity (the skull)‚ and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most

Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart‚ stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs and muscles within

The nervous system comprises the central nervous system which is made up of the brain and spinal cord‚ with the main functions being processing information and determining responses and the peripheral nervous systems which is made up of all sensory‚ motor and inter neurons within the body and these are located on peripheral nerves. All of them work together to collect sensory data and also control the actions of the body. Sensory neurons collect sensory information and convey it to the brain‚ and
