Warm up 5/5• Tomorrow we will meet in Rm 151
– 2nd science room from front of the school• Take the histology lab and turn to page 3.
– Come to the front and get 1 microslide viewer and one microslide strip. (Groups of 2)
– Look at 3 different slides. Draw pictures of the slides in the field of views provided on page 3 of the lab.
– Answer questions 10-14– Must clean up by 2:00 pm
MUSCULAR SYSTEM IIPP. 920-922
MUSCLE STRUCTURE CONT.
• Ligaments connect joints• Tendons connect muscle
to bone • When the muscle moves,
the bones move, and the joint bends
MUSCULAR MOVEMENT
• Muscles arranged in opposing pairs and while one relaxes the other contracts
flexor: contraction bends the joint extensor: contraction straightens the joint
MUSCLE FATIGUE
• The inability to contract the muscle due to the lack of ATP
SKELETAL SYSTEMfor dummiespp 911-916
RED= ImportantBLACK = Write Down BLUE = Don’t write down
FUNCTION
• Bones support muscles and organs• produce red and white blood cells• gives shape and structure to the body• protects internal organs• store minerals
SKELETON
• Axial –the skull, face, vertebral column, and rib cage.
• Appendicular –the arms and legs, pelvis, scapula, collar bone, etc
• bones and their associated tissues (cartilage and ligaments) make up the skeletal system to support the body
BONE STRUCTURE
• porous and made of proteins and minerals
• osteocytes –cells that make bone
• bone marrow – soft bone tissue that produces platelets and blood cells
BONE DEVELOPMENT
• develop from cartilage (tough flexible connective tissue)
• ossification: hardening of bone cartilage• elongation at the end of bones
JOINTS
• place where two bones meet
• Fixed: no movement between bones (ex. skull).
• Semimovable: limited movement (i.e. rib cage and vertebrae)
• Movable 1. hinge – knee and knuckle 2. pivot – skull joins the vertebral column 3. ball-and-socket – hip 4. gliding – wrist and ankle (slide over one another)
JOINT STRUCTURE
• cartilage between joints for cushion• ligaments connect joints (bone to bone)
• Quiz Tomorrow • P 922 # 9, 10 (Due Tues)• Look at p 929 #7. Define parts of picture 1-4.
– Is this muscle elongated or contracted? (Due Tues)
• Problems p 922 # 5-7 Due Wednesday• Physiology Study Guide Due Thursday• Histology Lab (Due Friday)• Exam Friday: Intervention Wed & Thur
