Torsion- twisting of the embryo along the left-right axis (similar to the twist of the body when a golfer swings at the ball). MOST prominent in the 48-hour chick embryo Flexion- bending of the embryo along the anterior-posterior axis. In amniotes the tip of the head bends towards the heart. Types of flexion: cranial flexion‚ cervical flexion‚ pontine flexure‚ dorsal flexure‚ caudal flexure. ^Cervical flexure- ventral bend in embryo at transition between myelencephalon and spinal cord ^Dosal Flexure-

Cell Wall- The cell wall is a rigid structure outside the cell membrane that supports and protects the cell. The cell wall is made of tough cellulose fibers and other materials made by the cell. Analogy- In a restaurant the building itself supports the restaurant. It is often made of wood or concrete. Cell Membrane- The cell membrane is a structure that forms the outer boundary of the cell and allows only certain materials to move into and out of the cell. Food‚ oxygen and water move into

Joints and Movements The Joints Definition: A joint (articulation) is point of contact between bones or between bone and cartilage. Joint Classifications Joints are classified by: The degree of movement they allow The structure of the joint The three types of joints that we will look at are: 1. Fibrous joints 2. Cartilaginous joints 3. Synovial joints Fibrous Joints These joints are also called "fixed" or "immoveable" joints‚ because they do not move. These joints have no joint cavity

Sample Physiology MCQs 1. Compound action potentials can be graded responses. True 2. The sciatic nerve contains axons of both afferent and efferent neurones. True 3. The absolute refractory period of an action potential is the period after an initial stimulus when it is impossible to evoke another action potential with a second stimulus. True 4. The refractory periods of individual axons are important as they dictate the maximal action potential firing rate of a neuron. True 5. Compound action

CONCENTRATION AND DILUTION Physiology 1‚ Las Positas College Name: In science‚ concentration is a measure of the number of particles (solutes) in a given volume. If one room has 100 people in it‚ and a room of equal size has 50 people‚ one can say that the concentration of people in one room is twice that of the other. Quite simple‚ isn’t it? On a molecular level‚ consider whether you put one lump or two of sugar‚ or no sugar at all‚ in your coffee. If you use two lumps‚ you prefer twice

Zachary’s Story Unit 6 Case Study 1 AP2630 Rhonda Carter July 27‚ 2015 A. An ulcer starts by eroding the mucosa of the G.I. tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis? Absorption would not happen correctly some of the ingested and secreted may seep out of the lumen. This also could create a pathway of entry for pathogens
