objective lens produces a better image. INTRODUCTION Internal structure of animal is made up cells. Cells aggregate and forms tissue. Animal tissues are classified into four types on the basis of their functions – epithelial tissue‚ connective tissue‚ muscle tissue and nervous tissue. EPITHELIAL TISSUE The covering and protective tissues in the animal body are epithelial tissues. It covers most organs and cavities within the body and forms a barrier to keep different body systems separate. Example: Skin

ability to estimate weight of an object‚ the force and time at which our muscles must be contracted are examples of our proprioceptive ability. Examples of proprioceptors are muscle spindles also called stretch receptors and their associated 1a axons. These receptors make up the somatic sensory system that is focus on body sense or proprioception. The muscle spindle consists of several types of speacialized skeletal muscle fibers that are contained within a fibrous capsule. In the middle region

When skeletal muscle twitches fuse so that the peaks and valleys of each twitch become indistinguishable from each other‚ the muscle is in a state known as You correctly answered: d. complete (fused) tetanus. 2. When the stimulus frequency reaches a value beyond which no further increase of skeletal muscle force can occur

Describe the Cardiac Cycle The Cardiac cycle is a description of the activities that take place in the period from the start of one heart the next. The conducting system autonomically controls the heart beat impulses it is also called the cardiac conduction system or the nodal system. It is made up of six main components the sinoatrial node (SA-Node)‚ internodal paths‚ atrioventricular node (AV-Node)‚ atrioventricular bundle (AV bundle) or bundle of His‚ bundle branches and Purkinje fibres. Contractile

For this assignment we are looking at the skeletal system. The skeleton is the internal framework of our body. It is made up of three things; bones‚ cartilage and joints. Without these three things we would just be a heap of skin‚ muscle and internal organs. The skeleton is made up of 206 bones that are separated into two groups. Firstly‚ the Axial Skeleton. The Axial skeleton is made up of 80 different bones whereas the Appendicular skeleton is made up of 126 bones. The Axial Skeleton The axial

(NCBI)‚ depending on the task males or females were more or less resistant for the muscle group being used. Valley Center High School physiology students conducted experiments on muscle size and strength and muscle fatigue. With this in mind‚ the data the students collected from these labs and other sources shows how muscle size and sex have an impact on an individual’s muscle fatigue resistance. First‚ the muscle size of an individual determines how long they can withstand certain types of physical

Muscles are a Band or bundles of tissue in either the human body ‚ or animal body that allow contraction for movement. There are many muscles in the body. It is stated that there are over 650 muscles in the body ‚ and is said that there are possibilities of up to 840. Your whole body is a muscle. You have Muscles in your head‚ arms‚ legs‚ just about anywhere you can think of and as we progress in life and become of age our muscles may grow and get stronger ‚ or may deteriorate.
