Biology 3201 1. Unit 1- Maintaining Dynamic Equilibrium II Ch. 12 – The Nervous System (pp. 390-419) 12.1 – Structure of the Nervous System nervous system: a high-speed communication system which delivers information to and from the brain and spinal cord and all over the body. In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves)

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Orthopedic - Muscular 1)The muscle that runs on a diagonal from the lower ribs to the iliac crest is the: A)rectus femoris muscle. B)external abdominal oblique muscle. C)latissimus dorsi muscle. D)rectus abdominis muscle. 2)The patient with cerebral palsy was described as having ataxia. This means that the patient: A)has slow skeletal muscle movements of his upper extremities. B)has slow‚ purposeless writhing of his hands. C)walks with an uncoordinated gait. D)has muscle jerking and spasms when

main tissues of the body. In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue. The first type of tissue found

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

Premium Muscle Myosin Muscle contraction
Skeletal muscle moves because we want it to. It is controlled voluntarily (consciously). There is 2 types of contraction Isometric: As the muscle contracts‚ it remains the same length whilst the tension increases in an attempt to overcome the opposing force. Example: Holding a glass of water still in front of you. Isotonic: As the muscle contracts its length changes whilst the tension remains constant or develops to overcome the opposing force. Example: Lifting a glass of water to your mount and

the cerebrospinal fluid is to protect the central nervous system. Layers of Meninges Dura Mater – means hard mother‚ the outermost w/c is tough & flexible. It surrounds & supports the large venous channels carrying blood from the brain toward the heart. Arachnoid membrane – the middle layer‚ so named because of its spider web-like appearance. It provides a cushioning effect for the CNS. Pia Mater - very thin membrane composed of fibrous tissue covered on its outer surface by a sheet of flat cells
