bio tissue

Monitor what’s going on our body Responds to change homeostasis

fire, inside blood vessels that monitor oxygen intake Sensory input→ integration→ motor output

carry info in and respond out

dense fibrous connective tissue

delicate, can’t see it

separates two hemispheres of brain

Separates cerebrum from the cerebelli

separates the two hemispheres of the cerebellum

flows through deepest part of brain, carries waste away from neurons, carries nutrients and glucose towards neurons

filled with cerebrospinal fluid

hole that fluid from lateral ventricles flow through

in diencephalon ,CSF flows through cerebral aqueduct and into fourth ventricle

A triangular chamber between the pons and cerebellum in the brain stem. Lateral apertures allow CSF to flow into subarachnoid space. narrows caudally to form the central canal that extends through the medulla oblongata into the spinal cord

The exact spot where u have ependymal cells making CSF

the brain

venous sinuses

arteries (superficial to dura mater) fast high pressure bleed (medical emergency

vein tears (most common, slow bleed, accumulates over time) -headache, repeats themselves without realizing they said it already -senior citizens usually

nerves, ganglia, sensory receptors and efferent nerve endings.

cluster or neuron cell bodies

consciously aware sensory input (eyes, ears, skin)

not consciously perceived sensory input (heart)

motor output that is consciously or voluntarily controlled (effector skeletal muscle)

not consciously or involuntarily controlled (effector cardiac & smooth muscle, glands)
