Inside the bone is mostly hollow, what is inside, for what?
Bone marrow, this is where blood cells are made.
Joint is:
point where 2 or more bones meet
3 types of joints are?

what is hinge joint? and example
has movement in o in direction, knees, elbows
pivot joint is?
allows side to side direction, neck and spine
what is ball and socket, and example
roun d on one end and hollow end of the other, hip, shoulder
Cartilage is?
connective tissues that cushions the joint so that the bones don’t rub together
what is Synovial membrane and secretions?
lines the joint and secrets the synovial fluid, provides ease of movement
what is ligament:
strong band of connective tissue that hold the joints together
how many muscles in the body?

Cerebrum is?
the centre of the brain used for thought and intelligence
2 halves of the brain are?
left and right hemisphere
outside the cerebrum is the cerebral cortex controls the highest functions of the brain:
reasoning, memory, speech, vision, hearing, sensation, voluntary muscles.
Cerebellum is:
co-ordinates and regulates body movements, balance
Brain stem is responsible for?
basis vital life function
what does the brain stem consists of?
contains mid brain, pons, medulla
mid brain and pons do?
relay messages between the medulla and cerebrum
medulla controls ?
heart rate, breathing, swallowing, coughing and vomiting
spinal cord is how long
approx. 45 cm
The spinal cord functions are:
contains pathways that conducts messages to and from the brain
Meninges is?
connective tissue that covers the brain and spinal fluid
Dura matter is:
tough outer layer next to the skull
Pia matter is?
middle layer, protects cerebrospinal fluid
Arachnoid is
inner layer that protects and cushions from shock
Neuron is?
transmits information
