Homeostasis = Body wisdom ↓ ↓ Steady state * Homeostasis keeps us healthy * The means by which organisms (our body) maintain a constant internal environment in spite of fluctuations in the external environment. * This means humans have narrow limits we have to keep. 1.

CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)

Neuromuscular blocking drugs were first used by South American Indians on their arrows to paralyze their prey. During that time neuromuscular drugs were called curare. They were first written about in a letter by a chronicler‚ employed by the Court of King Ferdinand and Queen Isabella‚ in 1516. In the 18th century Edward Bancroft‚ a physician‚ brought samples of curare back from South America and Sir Benjamin Brodie showed how small animals could be left alive after being injected with curare and

Vascular Dementia Vascular dementia is a common cause of dementia in the elderly. Dementia is a condition that affects the brain and causes people to not think well or act normally. Vascular dementia is one type of dementia. It occurs when blood clots block small blood vessels in the brain and destroy brain tissue. Likely risk factors are high blood pressure and advanced age. This disease can cause stroke‚ migraine-like headaches‚ and psychiatric disturbances. SYMPTOMS Confusion. Problems

Lab #3: Isotonic contraction and the effect of load on skeletal muscles Abstract The job of the motor nervous system is to control certain elements in muscles simultaneously to ultimately produce movement. Movement of the body is the result of specialized cells directly associated with skeletal muscle. Skeletal muscles are voluntary muscle and must contract before movement can occur. We know the muscle team moving the arm is formed at the biceps and triceps. Biceps can bend the elbow‚ but

When a muscle fibre is contracted this occurs in reaction to an electric signal from the nervous system. A motor neuron is a nerve cell that links and innervates many muscle fibres. The space in the middle of the motor neuron and muscle fibres is referred to as a neuromuscular junction where communication between the nervous and muscle system arise according to (Kenney & Wilmore and Costill‚ 2015). A series of events that triggers the muscle fibre to contract is termed

About 300 soft bones. they turn into 206 adult solid bones- If we can have a strong core – and deep abdominal muscle called “tranferus abdomenus”- wraps around your core- because it wraps around when it tightens ‚ it tightens up around the spine and gives it a lot of stability- the spine ( a whole lot of bones sitting on top of each other) we don’t want
