Comparative Vertebrate Anatomy Lecture Notes - Skeletal System II (Skull) The Vertebrate Skull consists of: 1 - neurocranium (also called endocranium or primary braincase) 2 - dermatocranium (membrane bones) 3 - splanchnocranium (or visceral skeleton) Neurocranium: 1 - protects the brain 2 - begins as cartilage that is partly or entirely replaced by bone (except in cartilaginous fishes) Cartilaginous stage: neurocranium begins as pair of parachordal & prechordal cartilages below the

Exercise 1 (20 marks) 1. What happens to the blood pressure and heart rate when the arterial resistance is increased? When arterial resistance is increased‚ the blood pressure increases and heart rate decreases. For instance‚ when arterial resistance increased to 150%‚ systolic blood pressure increases to 132.8mmHg‚ diastolic pressure increases to 82.1 mmHg‚ and heart rate decreased to 51.8/min. 2. What might give rise to condition with increased

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-

2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. If you lose a lot of blood‚ erythropoiesis will speed up; anemia can cause erythropoiesis to slow down

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

“ Ageing is a continuous‚ complex‚ and dynamic process that begins with birth and ends with death. And unless we die in our early years‚ each of us will grow old and experience the effects of the ageing process”. (Pirkl‚ 2009). The ageing process and why changes have taken place in the last fifty years. This report discusses the ageing process and why changes have taken place in the last fifty years. The ageing process is a change in an organism overtime and can be referred to as a multidimensional

Instead of assuming catcher position for practice she should begin a resistance program dealing with her quads‚ such as using 5 lbs. elastic bands attached to an Olympic bar and performing 5 sets of 10-15 squats to train her muscles and keep them loose. Also incorporating the 5 lbs. band and tying it to the bottom of a
